Fix Random Black Box Popping Up And Disappearing In Windows

Some of our clients are having issues with a random or intermittent black box popping up while they are working (starting around June 2017). This is an issue with Microsoft Office and can be resolved by doing the following.

  1. Click Start
  2. Start typing task scheduler
  3. Drill down to Task Scheduler Library – Microsoft – Office
  4.  If available, right click on OfficeBackgroundTaskHandlerRegistration and click Disable
  5. If available, right click on OfficeBackgroundTaskHandlerLogon and click Disable
  6. Close out of Task Scheduler

If neither of those options are available you likely have a different issue.
