Free up space on the main Windows C:\ drive. There are many large logs files in the Windows folder. Clean them up with this command which deletes all the way down the Windows doc tree.

cd windows
del *.log /a /s /q /f
Change directories to folder at top of directory tree you wish to clean (such as W3SVC logs folder) and clean it up.
