Hi Romanian, Sorry for the late response. I checked my C drive size. if i exclude hibernation file and page file the size is a little over 7GB. I have Virtual box installed which account for most space. of the installed programmes. (couple of hundred MB) But the virtual OS is on D Drive. winsxs account for about 4GB space of those seven. Hope this gets you a good picture of the install:) Regards /Frewys
