Typically, when running the installation file for WSUS to install it after an uninstallation, you will be prompted with the uninstallation screen a second time. This is because even though you may have selected to remove all of the components, the uninstallation doesn’t always remove all of them.
The best way to remove everything completely is to clean it with Microsoft’s Windows Installer CleanUp utility. You can download this utility at: http://support.microsoft.com/default.aspx?scid=kb;EN-US;290301. Simply install it, run it, select WSUS from the menu, and choose Remove. After doing this WSUS should be completely removed from your system.
