paradoxal problem w/ "application information service"

Hi there,

As I've mentioned in another topic before, I've had mysterious problems with my laptop and windows 7. Somehow, totally random my computer loses connection. When restarting it's stuck at "shutting down" . I've now figured out a work-around for the stuck at shutting down problem. I use a batch file for stopping the services "windows audio" service and "multimedia class scheduler" service, that runs at logof.

However, I still keep losing connection, so I went on with my search for the problem. In my log files i kept finding "application information" service... I read the description at the service managment window (accessed through ctrl+alt+delete --> task manager --> services --> button "services"), right clicked the service and set the startup setting to "disabled", and I should NEVER HAVE DONE THAT......

Now, I don't have any access to any program that needs admin priveleges. These include uninstall programs, but most important, all windows configuration programs, like system restore, regedit, and most import, service manager......

Does anyone know what to do in this situation? Is there a way to set "application information" service run settings back to "manual"?

Thanks for your help Brink/Shawn, did the system restore with the install disk, and worked like a charm! (kind of stupid of me to forget the option to repair windows installation with install disk, :$)
