On some occasions I found that when you create a paging file on a partition, and then when you decide you don't need it anymore and choose "No paging file" in the virtual memory settings, the pagefile.sys on this partition is not being removed by windows (wasting hundreds of megabytes if not gigabytes). CCleaner could check if a paging file is used by windows and remove the files that are not in use.

I see the reason why this should not be added, mostly because ccleaner deletes thing a system, not user or admin. Thus this can harm your system. If you happen to turn it off, and your system sys its not using it but you havent rebooted it can cause loss of data, if not worse. Now if there was a way to see if the file is being locked per say ccleaner check as a admin like the program unlocker, it could be posible.
