How can we help you?
You just said it cleans more.
What options do you have checkmarked in CCleaner?
The items you set it to clean make a LOT of difference.
What version of CCleaner do you use?
Version is very important because certain features & cleaning locations may be included in the last few versions that did not exist prior to that.
Did you check whether you also cleared System Restore points somehow?
Check with CCleaner to see the # of restore points before & after you do a disk cleanup.
Perhaps there is something CCleaner misses such as some dump file, but it would help to be able to know more first.
Also, check to see if hibernation is turned on or off. Hibernation files can take several GB depending on your system RAM & setup.

If possible, try this & reply back:
After using the PC a while, run CCleaner in Analyze mode & write down the GB it shows for cleanup.
Be sure you have the Memory Dump files etc checkmarked in CCleaner first.
Go to start/run & type cleanmgr /sageset:01
That should bring up cleanmgr with a few more options.
If you have trouble running it from 7, try installing Classic Shell & then run it in that run box.

Verify & write down the free space before beginning, then:
Test each option by checkmarking only the first item, then try only the second item checkmarked, etc.
Verify the GB before & after each item you checkmarked.
After completing all of these items, see what the final GB is & write it down.
_________________________________________________________________________
Send a log of the amount of space cleaned by each item you checked, along with the total cleaned by this process & the total that CCleaner showed in Analyze mode.
This will greatly help as it will help to determine which area is the most responsible for trash.
