You will see many websites out there that give you 101 ways to fix this, and NONE work or they will even have you delete ALL the tasks. NOT GOOD.

I have found an easy way to fix this:

  • Go to: C:\Windows\System32\Tasks\Microsoft\Windows\Windows Activation Technologies
  • Copy both Tasks to your desktop. (ValidationTask and ValidationTaskDeadline)
  • After you copy them to your desktop. Delete both of them in that folder.
  • Now, Open up Task Scheduler.
  • In Left Pane, Click on Task Scheduler Library, then Microsoft, then Windows, then Windows Activation Technologies
  • In the Top Middle Pane. Right Click and select Import
  • Import BOTH of the Files you copied to your desktop.
  • Once both of them are imported, you are done.
  • NO MORE PROBLEMS!
