I know that it is a life time ago (or so it seems) but I have a memory of Microsoft having a downloadable thingy that was able to check out ones own PC for any possible problems when installing Windows XP. Of course, now when I would like to use it, it seems to have disappeared off the face of the earth. Has anyone any idea where I could find it please. Its as though it has been erased from all my printed material and carefully retained mag. CDs. In hopes.
