JSI Tip 3655. How do I uninstall a Service Pack if the $NTServicePackUninstall$ folder exists but the Add/Remove Programs entry is missing?

If you need to uninstall a Service Pack, but the Add/Remove Programs entry is missing, you can navigate to the hidden %SystemRoot%\$NTServicePackUninstall$\Spuninst folder. Run spuninst.exe.

NOTE: If the %SystemRoot%\$NTServicePackUninstall$ folder is missing, you can not uninstall the Service Pack.

NOTE: If an Add/Remove Programs entry exists but the %SystemRoot%\$NTServicePackUninstall$ folder is missing, use tip 0034.
