Here are some things you can do to recover some of the disk space:

Also, the community Win10 Forums has the following suggestions:

In addition, I have found the utility Cleanmgr+ to have LOTS of options for removing Windows junk, including log files. I use it practically every day. You can get it from here: https://www.getclone.app/download/category/11-cleanmgr

Also, there is a freeware app known as Wise Disk Cleaner. I use it every day to get rid of junk files: https://www.wisecleaner.com/wise-disk-cleaner.html

Hi WAWood

Thanks for help.

I did all this to free up space on C drive and now I have found out there is around 142 GB unalocated space on the 256 SSD drive.

with disk management in Windows it must be able to add this space back to C drive.

if you right click on C drive there is the option extend volume to run but this option is gray-out.

I run this PC as admin so what is going on here?

Those routines free up ALLOCATED space to make room in the existing OS drive; they have nothing to do with Unallocated space -- that is outside any of the drives.

You would need to post information on what Disk Management shows for assistance from here.
