Freeing Disk Space on C:\ Windows Server 2008

Freeing Disk Space on C:\ Windows Server 2008

I just spent the last little while trying to clear space on our servers in order to install .NET 4.5. Decided to post so my future self can find the information when I next have to do this.
I performed all the usual tasks:

• Deleting any files/folders from C:\windows\temp and C:\Users\%UserName%\AppData\Local\Temp
• Delete all EventViewer logs
  
  • Save to another Disk if you want to keep them
• Remove any unused programs, e.g. Firefox
• Remove anything in C:\inetpub\logs
• Remove any file/folders C:\Windows\System32\LogFiles
• Remove any file/folders from C:\Users\%UserName%\Downloads
• Remove any file/folders able to be removed from C:\Users\%UserName%\Desktop
• Remove any file/folders able to be removed from C:\Users\%UserName%\My Documents
• Stop Windows Update service and remove all files/folders from C:\Windows\SoftwareDistribution
• Deleting an Event Logs
• Run COMPCLN.exe
• Move the Virtual Memory file to another disk
