According to Windows, my machine can no longer display the Aero interface as an application is using a "mirror driver". I can't think of any software I've installed recently that would need to mirror my display, so is there a way for me to find out what application is causing this problem?
You should be able to find this information in the
Device Manager. It should be located in the
Display Adapters section.
Commonly this problem is associated with remote administration software such as LogMeIn, UltraVNC, TightVNC, Radmin and RemotePC.
