Change the name of the registered user.

When you install Windows, you're prompted to enter a username and a company name. But since it's fairly common for companies to merge, you may want to change the name of the company Windows is registere to by using this hack:

1. Navigate through the Registry Editor to HKLM\Software\Microsoft\WindowsNT\CurrentVersion.
2. Change the values that are assigned to the RegisteredOwner and RegisteredOrganization keys to reflect the new ownership information.
