Good news and no problem at all. We have an academy here where we teach users how to fix Windows Update/Servicing issues. All that we ask in return of our time is that you stick around and help some users on the forums. If it's something you are interested in, let me know.
The specific use of FRST is not taught here. I've had extensive malware removal training and this is the primary tool that is used. Since I had the knowledge of the tool I was able to use it. There are other ways to accomplish the same thing however that are taught at the academy.
Take care!
