If you mistakenly typed an incorrect registered user and/or company name when instaliing Vista and find yourself looking for a way to change it, you've come to the right place. Here's how its done:


- Press Windows key + R (This will bring up the Run dialog)

- In the Run dialog box type regedit and press Enter

- Once Registry Editor is opened navigate to the following:
HKEY_LOCAL_MACHINE\Software\Microsoft\Windows NT\CurrentVersion

- On the right hand window pane you will see multiple String and DWORD values. Look for RegisteredOrganization and RegisteredOwner [See pic below]








- You can double-click on each and change them to whatever you like. Click OK after typing.

You can now close the Registry Editor and were done. This does not require a reboot.

NOTE: This method works for Windows XP as well.
