I noticed that my laptop’s C: drive was running out of space, so I decided to delete temporary files, old updates and dump files. Probably easiest&fastest way to do so is to use built-in Disk cleanup utility.
Click on Clean System Files and review/mark all the „Files to Delete“ options:
My total amount of disk space gained by cleaning up my disk is 8.62 GB – so not bad 🙂
Note that on Windows Server, Disk Cleanup is part of Desktop Experience. I found it especially useful for cleaning up WinSxS folder.
