I found a topic where my problem has been discussed:
ccleaner
I also noticed that several of my, apart from MS defender, shortcuts as mentioned in the topic have been deleted.
Like defrag, system restore, remote desktop etc.
How can I restore these shortcuts. Does anyone know?
I see you are busy with it. (I did by mistake not enable notification by e-mail, so assumed no replies were send)
For now I will use the cleaner only and leave alone the register clean.
Sure hope you will be able to figure it out as I love Ccleaner.
Bye
