If you�ve ever wondered how to change the name of the person that Windows is registered to, this is the quick tip for you. It�s not all that useful, but it might come in handy if you got a computer from somebody else.
Open up regedit.exe through the start menu search box, and then locate the following registry key:
HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion
Now you can find the RegisteredOwner and RegisteredOrganization keys in the right-hand pane. Change them to whatever values you want.
To show off the new changes, just type winver.exe into the start menu search box to see the About Windows box:
"By The 'How To Geeek'! "
