This feature Controlled Folder Access  only works when Windows Defender Antivirus is your main security software; if you're running third-party antivirus on your machine, this feature won't be available.

Thank you,

 

You've given me an idea about what may be stopping my word processor and spreadsheet saving to the Documents folder when they can save to the OneDrive folder.

That too started with the FCU.

 

OneDrive is not in the CFA list.

 

I'll try allowing them in CFA when I get home.

Thanks again for your help - It would be interesting to know if that worked for you ..

Did you possibly make a mistake and allow CCleaner.exe instead of CCleaner64.exe?

 

Have you tried allowing both?.

 

BINGO!

It looks like yes I made the mistake and allowed CCLeaner.exe -  when it should have been CCleaner64.exe

Setting it to CCleaner64.exe   - seems to have fixed the issue I was having.

 

Thanks for your help

But still get the popup notice on the windows action center
