[box type=”shadow” align=”” class=”” width=””]HKEY_LOCAL_MACHINE -> HARDWARE -> DESCRIPTION -> System -> CentralProcessor -> 0[/box]


  • Find the key with name ‘ProcessorNameString’
  • You will see the name of the processor with model and CPU clock speed. Change it to whatever you want. That’s it.


Modify at Every System Startup

But the problem with the above free trick is that the changes are temporary and once you restart the computer, the changes are lost and the values are reverted back to original. We have a solution for that. You can create a registry entry to update the values every time the system restarts. Let us see how to do that.

  • Open notepad and type exactly the following content.

[box type=”shadow” align=”” class=”” width=””]Windows Registry Editor Version 5.00

“ProcessorNameString”=”My Processor name 50000MHz”[/box]

  • Save it by clicking File menu and select ‘Save As’. Give it a name as ‘ProcessorNameString.reg’ and choose ‘All Files’ in Save as Type option.


  • Create a shortcut on desktop by right clicking and selecting New -> Shortcut. 
  • In location of item, type regedit /s and then in double quotes the location of the file which you have created in previous step. Click Next and then Finish.

  • Now we have to place this shortcut in the windows startup folder.
  • Copy the shortcut and navigate to the below path and paste it

[box type=”shadow” align=”” class=”” width=””]C:\Documents and Settings\All Users\Start Menu\Programs\Startup (Windows XP)

C:\Users\yourusername\AppData\Roaming\Microsoft\Windows\Start Menu\Programs\Startup (Windows 7, 8, 10, Vista)[/box]

Note that the folder AppData is a hidden folder. And ‘yourusername‘ is your own windows user name.

Now the registry file will execute every time the windows starts up and the changes in system properties will never change.

Using this trick you can fool someone. Or you can avoid getting fooled by someone. For example if you are planning to buy an old PC/Laptop, then do not just trust the configurations by seeing system properties.
