Certain startup entries can't be deleted (only enabled, even though they are already)

I'm running Windows 8.1 x64 on an ASUS laptop.

I can't delete the start up entries that were installed by the OEM (they don't even show up in the task manager, which is weird). They show up greyed out and I can activate them (even though they are active), but deleting them results in an error message.

The message is in german, it translates to: "The system can't find the object. "

Everything that I installed I can change without a problem. Is there a solution to this?

Have you tried disabling them instead of deleting them as a non-destructive alternative?

If CCleaner also can't disable them you could try using msconfig which is built into Windows.

Everything you see in the picture that is disabled, can only be enabled and not deleted. But everything is in fact enabled (as in: it's loaded at system start). You see?

I've tried msconfig, but it doesn't show the entries either, just like the Task Manager.

I really don't understand what's happening here. I've used CCleaner on dozens of systems and never once have I seen such behaviour.

- If you select a line then does the text on the buttons on the top right hand side show up black characters ? Sometimes the combination with other installed programs interferes with Ccleaner form working properly.

have you tried starting CC with Run as Administrator ?

You mean "Activate" and "Delete"? They show up black, yes.

Yes, is doesn't make a difference.

- Run the program is Safe Mode. Perhaps then you can remove those entries ?

- Perhaps the permissions are modified and then one can't remove them. Try if running "Tweaking's windows Repair" (www.tweaking.com) will help to solve the issue.
