My OS Disk was almost full (700 MB remaining) and to clean the drive, i have tried disk/system file cleanup but hardly i got any space
After doing some system search i was able to find a manual way to deal with the issue and luckily it worked just perfectly.
Run the CMD in admin mode and key in below command to delete all temp files
C:\windows\system32> del /q/f/s %temp%\*
Now i got 20 gb on OS drive
Happy daxing
