Why is the Windows folder 62 Gb??

Question

Windows

My C/WIndows folder weighs 62 gb!
How can she take so much? I went through the Ccleaner program, but the place is still occupied by 62 gigs. You may need other special utilities to clean up this folder - well, there's a lot of garbage there for sure!

Delete everything, it is not needed at all.

Answer 3

I think it would not hurt to know what exactly weighs so much there.
First check the Temp folder

Answer 5

Most likely, update uninstallers in hidden folders like $NtUninstallKB... weigh the lion's share.
And if you don't plan to rollback, you can delete them.
