how do I change the registered name in Windows 7 to my own name?

Via a registry tweak:

• Press Windows Key+R and type regedit. Then press Enter.
• Navigate to:

  HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion

As seen above, you can see the RegisteredOrganization and RegisteredOwner. Double-click either to change the registered owner/organization!

To confirm changes, just type winver.exe in the Start search box or in the Run Command dialog box, and you should be able to see your changes without a restart.
