The couple of windows images seem to create problems for the linux images in that linux seems to work better together but with windows hogging the memory (worst case is a win7 and win8 running concurrently, nether play well.) Have not looked further than reducing the memory allocated to windows (which triggered a genuine windows check on win7!) so they co-exist "uneasily"
