I tried to move "opera_autoupdate" folder from "C:\Users\Teacher" to "C:\Users\Teacher\AppData\Local\Temp" and the action can't be completed because the folder or a file in it is open in another program.

When Windows 7 booted up, Opera Browser Assistant has stopped working. Here's the technical details:
