Hi All,
I am stumped on how to fix this problem. When using the writables volumes on W7SP1, the writables volumes is randomly being filled up to 0% and VDI will either lock out the user, or all applications will just crash. I used treesize to see what is filling up C:\, but I did not see anything out of the ordinary other than WinSXS being fairly large. I ran through all the steps on optimizing VDI, disabled all updates, and did disk clean up.
