Thanks stalion, I think I might have misled you a bit, I shouldn't have said user name, I meant the first name that goes in, probably Admin. or some thing like that. The one the computer belongs to. If you get what I mean. Cheers, gedr.
In the Registry Editor, drill down to the place where you see the following: HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows NT\CurrentVersion.
In the right pane, double-click RegisteredOrganization. In the box under Value Data, change the name or leave it blank. Double- click RegisteredOwner. Change the name to your own. Close the Registry Editor.
