In tip 5889 ยป How do I remove the Set Program Access and Defaults feature, I described how to remove the Set Program Access and Defaults feature, after it is installed.

To remove it during a service pack rollout:

1. Expand the <service_pack_name>.exe file by running <service_pack_name>.exe /x.

2. Open the <Extraction Folder>\i386\update\Update.inf file in Notepad.

3. Under the \[Product.Add.Reg\] section, add the following line:

HKLM,"SOFTWARE\Microsoft\Windows\CurrentVersion\Policies\Explorer","NoSMConfigurePrograms",0x10001,0x1

4. Save the <Extraction Folder>\i386\update\Update.inf file.

5. Install the service pack by running \\ComputerName\ServicePackShare\i386\update\Update.exe, where \\ComputerName\ServicePackShare points to <Extraction Folder>.
