Kiddo has Win 2007 on a Dell desktop and Windows resides on a 30GB C drive. WINSXS has balooned to the point where the drive is full and I can't even get SP1 on there because not enough space. So no way to shrink it. There's also a separate 250GB drive in there that just has data and apps. If I don't care about preserving data on D: drive or C: drive - is there a way I could migrate Windows to the D drive short of doing a fresh installation from CD/USB? Thanks.
