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, 8 or 8.1) 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.

Change Processor Name Permanently

A while ago I published an article on changing your processor name. But recently, Anil Kumar pointed out that the trick only changed the name temporarily.

After a user restarts his computer, the name reverted back to original which is obvious as each time Windows boots, it checks the connected hardware and updates the registry value automatically. So, changing the processor name using the earlier article did not have permanent results.

Thus, the alien processor name you had earlier again reverted back to the boring old one.

Problem: To, make the name change permanent, it was required to update the Processor Name String registry key every time Windows starts.

Solution: It is very easy to change your processor name permanently by creating a registry key and placing a shortcut to it in the Windows start up folder. To do so, just follow the steps given below:-


Steps :-
1.  Open Notepad.
2.  Copy and paste the exact code given below:-

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor\0]
"ProcessorNameString"="My Processor name 50000MHz"

To change the processor name, edit the part of the code given in blue. Also understand that \0 in the above code should only be present if Windows store your processor name at that location. Open the Registry Editor and navigate to the above mentioned keys to check whether or not to include the \0.

3.  Click on File Menu, click on Save As and select "All Types" in the Save as Type option. Save the file as ProcessorNameChange.reg or *.reg.
4.  Create a new shortcut on your desktop. Enter regedit / S "Location of the .reg file" as the location of the item. For example, enter regedit /S "C:\Processor Name.reg" if your registry file is located in the root of C:\ drive.

5. Copy the created Shortcut file.
6.  Navigate to C:\Documents and Settings\All Users\Start Menu\Programs\Startup (in Windows XP) or toC:\Users\ User-Name\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup (in Windows 8, Windows 7 and Windows Vista. Also remember that AppData is a hidden folder.)  if C: is your System drive.
7.  Paste the copied file.


This registry file would now execute each time when Windows starts and the Processor Name String would be modified each time. This means that even upon restarting your computer, you will see that the changed processor name is permanent.
