This step-by-step article describes how to change the name of the company in Office XP after Setup by modifying the Windows registry. This article also explains how to change the user name information.

NOTE: In earlier versions of Office, if you want to change the company name that is displayed on the Office splash screens and in the About program name dialog box on the Help menu (where program name is the program that you are using), you must remove Office, run Setup again, and then type a new company name.

1.	Click Start, and then click Run.
2.	In the Open box, type regedit and then click OK.
3.	Try to locate and select the following key. If the key is not present, go to step 6. HKEY_LOCAL_MACHINE\Software\Microsoft\Windows\CurrentVersion\Uninstall\< GUID> where <GUID> is the Product Code for the version of Office that is installed; for example, {90280409-6000-11D3-8CFE-0050048383C9}. More than one GUID may be listed under the Uninstall subkey.
