Tired of tweaking? Well, Let us now do a very very simple registry trick. You can change the 

Registered Owner or Registered Organization to anything you want even after Windows is

• Navigate to:HKEY_LOCAL_MACHINE 
  \SOFTWARE\Microsoft\Windows\CurrentVersion.
•  Now Change the value of 
  "RegisteredOrganization" key or “RegisteredOwner", to what ever you want.
