This is a bit of a technical post that I wanted to just put out there in case someone else was having this issue. Anyhow, it's an error that shows up in the XP Event Viewer with the following details listed above:
Service Control Manager Error ID 7000
The Win Common module service failed to start due to the following error: The system cannot find the path specified.
So, here's how you fix it. It seems that Service Control Manager is trying to load a service module called Win Common. This is probably referring to something that was removed from my HD and so is generating this error. What I did was to run HiJackThis using the /ihatewhitelists mode. You can look up how to do this by googling it. I then found the service entry referring to this problem and removed it. Simple as that. Apparently these Service Control Manager Errors can be a nightmare. I hope you solve it.
