I have a an sbs2011 standard user. Sharepoint is OFF. What is eating about 300 megs a day in space on my C drive? I looked for logs and saw nothing odd, no large files. Could it be WSUS? I am concerned and do not know what to do. What should I look for? We do not use Exchange...I know, could but do not. Exchange is running though, otherwise I do not know what would happen.
