You are correct, Windows should protect C:\system volume information\,
which holds Restore Points plus other stuff.
I think you or a utility has broken Windows.
There is no way that CCleaner should be even seeing the contents of
C:\system volume information\
I have just downloaded the Portable version 3.22 of CCleaner.
I have added one file to my computer
C:\tracking.log
I have included that in my custom files with the non-default setting of
"Include files, subfolders and the folder itself"
I then created a further file
C:\Users\Alan\AppData\tracking.data
Then I performed Analyze which found many files, including
C:\tracking.log and
C:\Users\Alan\AppData\tracking.data
which shows my "include" penetrates through all the subfolders to which CCleaner is given access.
even so CCleaner never detected the presence of
c:\system volume information\tracking.log
TreeSize Free shows me everything that occupies space on my drive, which includes
c:\system volume information\tracking.log
which has a size of 20.0 KB (20,480 bytes)
TreeSize Free has super powers that show me what Windows does not want me (or CCLeaner) to see.
I too have super powers and by using iCalcs I do what I like with c:\system volume information\tracking.log,
and with that tool I can allow CCleaner to see and delete the contents of c:\system volume information\
but I prefer to avoid breaking Windows.
It is highly dangerous to start at the root of C:\ and delete all files with a specific name.
You may have changed the self protection of Windows by removing from less protected system folders anything that matched
~*.*
Another program I use, Cleanup!, can handle the wildcard fine
If that is a legitimate program. that may have weakened Windows defences.
The fact that an internet search does not identify what it is or where it came from makes me wonder of "Safe Search" is keeping me away from malware downloads ![:rolleyes:]()
