How to get rid of 75 GB of temp files in Window 7?

[Guest]

My Windows 7 laptop has only 15 GB available on the C drive out of 283 GB. Much of the used-up space is from 1000s of temp files that don't disappear when I clear the cache. I downloaded a file analyzer but it doesn't help me know which files are OK to delete. I don't want to delete important operating temp files, if there are any there.

use ccleaner and disable system restore. Thats where some it may have gone. Temp files take up space

Do not disable system restore.
It is there to help you recover if you have a software caused failure.

Run windows disk cleanup.
You find it in accessories/system tools.

I didnt say you couldnt turn it back on

It can also harbor malware if youre infected. IMO SR is hopeless. On these its off

If you get infected with malware, system restore can save you and get you back to the point before the infection.
You can limit how much disk space system restore can use.
SR space should not be any issue.

Close any open programs.
Click the start menu.
Under "Search programs and files", type "cleanup".
Click "Disk Cleanup"
Select the drive you want to clean and click OK.
Wait a few minutes for it to scan.
Click "Clean up system files"
Select the drive you want to clean and click OK.
Wait a few minutes for it to scan.
Scroll through the list and tick anything large, temporary files should be ticked by default.
Click "OK"
Click "Delete Files"
