when i right-click on my desktop "windows explorer not responding" message appears.windows hang out and i have to restart the windows again.

A lot of times when someone encounters this behavior, it can be due to explorer add-ons or shell extensions. 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.Try a clean boot, or boot into safe mode. Does the behavior persist?
