Getting Back A Deleted Windows Service

I have had a problem for months now, that sometimes data wouldn't copy or be deleted if they had anything to do with installing before. For example, if a program autoupdates itself and downloads his new .exe, then it might be unable to delete the old one, and the update failed.

This has become more of a problem recently, so through some research I found this solution: Originally Posted by Exhorder I probably found the 'real' fix for the problem.

Go to services and look for Application Experience Service (AeLookupSvc) - (Anwendungserfahrung in german), set the start type to manual. Then you are able to install from the usual executable (*.msi)

Deactivating that service can cause all sorts of problems, with alot of programs. It seems to lock up some .exe files after the program is already closed so it cannot be deleted or moved.

Try the following example:

Download TCPView, start it, close and then try to move the folder to another directory. It won't work unless the App..Experience Service is on manual because the exe file is still locked up for a while. ...where I am positive that it will work. (read it elsewhere too + alot of positive replies from people who described the exact same symptoms)

My problem is now, that this service is nowhere to be found on my computer. It might have been deleted by some virus-scan months ago (so no recovery points) when the problems suddenly arised.

I tried to find ways to manually get back a service, but wasn't that lucky. ..So what could I do?
