If you’re running across the following error in your event logs:

The machine-default permission settings do not grant Local Activation permission for the COM Server application with CLSID
to the user [username] SID [SID] from address LocalHost (Using LRPC). This security permission can be modified using the Component Services administrative tool.

Then you’ve probably edited or disabled the following windows task:
Task Scheduler Library/Microsoft/Windows/Defrag

By default it is set to run weekly. If you change it you will begin getting the error above. To fix the issue, undo your changes (set it to enabled and weekly, 1am every Wednesday of every week)
