Windows Explorer 7 is not responding - 'apphangb1 explorer.exe' error
For some reason quite randomly Windows 7 keeps crashing and comes up that Windows Explorer is not responding with the below error. Do you know what could be the issue at all as it's quite frequent so you can imagine my frustration. So far I have run Microsoft
Security Essentials, Disk Cleanup, Disk Defrag, Registry Mechanic and SFC scan and all has worked find with no errors.
A problem caused this program to stop interacting with Windows.

Often, instabilities in Windows Explorer are attributable to faulty shell extensions and addons.
Consider using Sysinternals Autoruns or ShellExView. Disable non-Microsoft shell extensions
and add-ons, and check the behavior. If it is gone, re-enable the disabled extensions/add-ons, one at a time, and see if you can identify which may be responsible.
