Here is a very quick and easy guide on how you can change the Windows registered owner. I’m sure this trick will not be that useful for most windows users but it can be handy if you got a machine from somebody else and don’t want or don’t have the proper knowledge to perform windows installation.
Open your registry editor by typing regedit at the search menu and locate the following key.
Look for the RegisteredOwner and RegisteredOrganization keys in the right-hand pane then Change them to whatever values you want.
Now, to see the changes, just type winver into the start menu search box.
This trick works on all versions of Windows including Windows XP.
