taskeng.exe keeps running

Hi !

I am testing ccleaner /AUTO with Task Scheduler in most cases run well as I expected

but I would like to ask why in some computers a black window with the process name taskeng.exe keeps running during the his task,

in most cases this window just appear for short time like 1 second.

I wondering if anyone saw this behaviour before,

How can I explain this behaviour?

Thanks

Regards

You have Skip UAC enabled, yes?

This feature uses a windows task to accomplish its mission.

taskeng.exe is process for Task Scheduler, so it might be some process is scheduled to run at this time. But some malwares also can use taskeng.exe,

Yes but in this case it's likely to be SkipUAC
