I was recently looking for a way to change the processor name displayed on properties by right clicking on My Computer. Although the web was filled with a lot of such tutorials, I was surprised to find that the processor name went back to the original one after I restarted my computer. This surprised me as I did not expect this to happen. After looking for a workaround, I discovered a way in which this can be done. All I needed to do was to create a registry file that would auto execute each time I logged to on to my PC. This could be achieved by the /s registry operator. Given below are the steps I used to achieve this on my computer.
Steps :-
1. Open Notepad.
2. Paste the code given below:-
3. Save the file as *.reg.
4. Create a new shortcut on your desktop. Enter regedit / S " .reg file". For example, enter regedit /S "C:\Processor Name.reg" if your registry file is located at C:\ drive.

Steps :-
1. Open Notepad.
2. Paste the code given below:-
Windows Registry Editor Version 5.00
[HKEY_LOCAL_MACHINE\HARDWARE\DESCRIPTION\System\CentralProcessor\0]
"ProcessorNameString"="My Processor name 50000MHz"
3. Save the file as *.reg.
4. Create a new shortcut on your desktop. Enter regedit / S " .reg file". For example, enter regedit /S "C:\Processor Name.reg" if your registry file is located at C:\ drive.
5. Copy the Shortcut file.
6. Go 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 7 and Windows Vista .
7. Paste the file.
