How to Fix Multiple taskeng.exe Instances Problem

Sometimes multiple taskeng.exe processes start and never end. This can slow down your computer, as this huge number of taskeng.exe processes can consume quite a lot of system resources. On top of that, you might start getting various Task Scheduler errors, such as “The task image is corrupt or has been tampered with”. Luckily, it’s pretty easy to solve this problem:

  1. Click on Start and type task scheduler in the Search bar. Press Enter and press Continue when you get the UAC prompt .
  2. Locate Task Scheduler Local on the left-hand side and right-click on Task Scheduler Library.
  3. Make sure the Show Hidden Tasks option is enabled under View.
  4. Now widen the Name column. The hidden task that is likely creating the problem has a name that starts with User_Feed_Synchronization followed by a dash and a bunch of digits inside a curly brace. Select this task by clicking on its name.
  5. Now go to the History tab and expand the Level and Date and Time columns. If the selected task is the culprit, you will see a whole load of errors that occur every five minutes.
  6. Now select Disable in the right-hand pane.
  7. Go through the tasks, as there might be other tasks causing the same error.
  8. When you are done, close the Task Scheduler and reboot your computer.


The taskeng.exe process is safe and disabling it can be dangerous because programs on your computer need it to work correctly.
