I tried this and did not work....then I installed Spybot search and destroy...now that doesn't work...I believe the culprit is the new Windows 10update I installed yesterday....don't recall the update numbers but took 2 hours to install...now I'm going to try to undo this major update.... That major update you got was the latest Win 10 build 10586. You would have to rollback to the last build. Do you have 2 antiviruses on your PC by any chance?
