Most PCs that I encounter have drives that are full. This was the case in the days of HDD, and with modern SSD typically being smaller it is even worse. A full drive will slow your PC down, as well as the annoyance of running out of space at a key moment. Here are a good range of ways of freeing up space
1. Empty the recycle bin
2. Uninstall unwanted / unneeded programs
3. Run cleanmgr.exe to clean up junk files
4. Run cleanmgr.exe including system files to remove unnecessary windows update files and other system junk
5. Delete all of the files in %temp%
6. Use Glary Utilities to remove lots of other junk files, including from common applications
7. Use Patch Cleaner to remove orphaned windows installer files
8. Delete old installer folders from the C: drive including “nvidia” “amd” “intel” “msocache” and others
9. Clear out old system restore files (or turn system restore off)
10. Run a disk check to make sure the amount of free space you have is correctly recognised
11. Use WinDirStat to identify any unexpectedly large folders to clean up
