You can change the registered owner’s name and organization that’s stored by Windows, viewable via the Windows winver.exe program. This is useful, for example, if your organization changes its name or is bought out, or if they buy used PCs. Changing the registration info isn’t extremely important, but can be useful as some program installers prefill their registration details with those from Windows.
To change the Windows registration info, change the value of the following two registry values:
Key: SOFTWARE\Microsoft\Windows NT\CurrentVersion
DWORD Name: RegisteredOwner and RegisteredOrganization
