To change the registered owner and organization details on Windows 11, use these steps:

1. Open Start.
2. Search for regedit and click the top result to open the Registry Editor.
3. Browse the following path: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion
4. Double-click the RegisteredOwner string.
5. Confirm the new registered owner information.

6. Click the OK button.
7. Double-click the RegisteredOrganization string.
8. Confirm the organization information – for example, “Family” for users or your organization’s name.

If you cannot find the strings, you may need to create them by right-clicking the CurrentVersion key, selecting New, choosing the String Value option, naming it “RegisteredOwner,” and then creating another one called “RegisteredOrganization.”

8. Click the OK button.
9. Restart the computer.

After you complete the steps, the system will reflect the new owner and organization names. You can confirm the new changes by using the “Windows key + R” keyboard shortcut to open the Run command and querying the winver command.
