    Great tips, most of them i knew, but that one on point 4 “Storage Sense” was unkown for me and did not help much (except for the part that can be enabled to auto-run) since i manually do (after a manual reboot after windows updates) a manual cleanup procedure (with a script i write), some tips: I delete: “%windir%\SoftwareDistribution\*” I delete: “%ALLUSERSPROFILE%\USOPrivate\UpdateStore\*” I delete for all user profiles “…..\AppData\Local\Temp\*” I delete: “%windir%\servicing\LCU\*” I clean up all events with “wevtutil.exe el” to list and “wevtutil.exe cl” in a loop to clean I clean up windows updates with “dism /Online /Cleanup-Image /StartComponentCleanup /ResetBase” And also clean up some more files with: cleanmgr “%SystemDrive%” Of course i run the script i made when it is safe to do it and in off-line mode.
