I restarted the system and I can change the file types again.
But now at boot I get an, Error: Loader couldn't initialize service! error.
I can hit OK and Explorer is not loaded. I can start it from task manager or I can log of at which pint it will automatically log back on. Explorer and all my startup programs will run and everything works fine.
The only thing as I said before, I cannot log of as the system logs back on immediately. Window-L to switch users works.
I have no errors in the event log.
This is not directly related, but since whatever caused me not to change the extensions before is causing this problem, maybe it can be fixed.
Is there any way to see the exact script that is running and fails and at what point and what service is not starting?
Thanks
