This step-by-step article describes how to change the name of the company in Office 2003 after setup by modifying the Microsoft Windows registry. This article also explains how to change the user name information.

Note In earlier versions of Office (before Microsoft Office XP), if you want to change the company name that appears 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.

To change the company name that appears in the Office programs, follow these steps:

1.	Click Start, and then click Run.
2.	In the Open box, type regedit and then click OK.
3.	Locate and then click the following key: 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. If you see more than one, select each GUID until you find the one that has the correct product name listed for the DisplayName value; for example, "Microsoft Office Professional Edition 2003". If the key is not present, locate and then click the following key: HKEY_LOCAL_MACHINE/SOFTWARE/Microsoft/Windows/Current Version/Installer/Userdata/S-1-5-18/Products/{GUID}/InstallProperties where GUID is the product code for the version of Office that is installed; for example, {9040820900063D11C8EF00054038389C }. More than one GUID may be listed under the Products subkey. If you see more than one, expand each GUID, and then look in the InstallProperties folder until you find the one that has the correct product name listed for the DisplayName value; for example, "Microsoft Office Professional Edition 2003".
4.	In the Name column, double-click RegCompany. Note If you do not locate RegCompany, go back to step 3 and locate and select the other registry key.
5.	Change the text in the Value data box, and then click OK.
6.	Locate and then click the following key: HKEY_CURRENT_USER\Software\Microsoft\Office\11.0\Common\UserInfo
7.	On the Edit menu, click Rename.
8.	Type OldUserInfo, and then press ENTER.
9.	On the Registry menu, click Exit. When you start an Office program, the company name that appears reflects the change that you made in step 5.
