How to change the Registered Owner in Windows 7
Most third-party applications pick registration details from the system and such details were inputted during the installation of Windows 7. The owner name and organization details stored in Windows can be displayed using the winver.exe application but cannot be modified through the GUI. What if, you need to change the registered owner or organization name? Say, you have bought a used computer or exchanged your computer with a co-worker and there’s no need to re-install the whole thing from scratch! You can directly change these details from the registry editor.
To start the registry editor, type regedit in the Start menu search text box and press enter.
Go to the following registry key and edit the RegisteredOwner and RegisteredOrganization values:
Key: SOFTWARE\Microsoft\Windows NT\CurrentVersion
DWORD (32-bit) Value name: RegisteredOwner and RegisteredOrganization
A word of caution – incorrectly editing the registry may severely damage your system. The above modifications are intended for Windows advanced users who are familiar with the registry editor. Users are also reminded to back up the registry before making any critical changes.
