Does your company have an IT department? If your employer owns the computer, they usually have provisions for backing up and repairing the systems they own. As a former BOFH, there were special torments reserved for sales droids that tried to fix their own computer and lost company data.
If it is a brand name computer, there are often methods of repair or restore that are built in.
Also note, the default setting for windows installer in services should be manual.http://www.microsoft.com/resources/documen...s.mspx?mfr=true
I recently had a system with a failed dotnetfix install that left the system in a state where the installer started up and left two msiexec processes running and windows installer restated them as soon as I killed them. I had to kill several processes and move installer back to manual. It seems the dotnet install script had set it to automatic rather than just calling it with a script.
Not sure if it is related but a perpetual running installer session will stop the install or uninstall of anything.
