We ran CC Cleaner, AVG Anti-virus, and installed about 40 Windows updates. We then shut the computer down and returned it to the customer. The customer booted up the machine normally, the OS started, the desktop came up, and then we had trouble connecting to the Internet. In our troubleshooting procedure we discovered under Computer Manager that all services had been disabled. Every last one of them. We have been able to re-enable the services and the computer appears to work normally, however, we are nervous because we do not understand what happened to disable all of the services. Of course we suspect an update, but what update could be that problematic? Can someone help us undersatnd why this happened and the likelyhood that it will hbappen again? Thank you.
