Sit down little boy. I haven''t dismissed you from class yet. As you just openly admitted, you don't get updates for Windows XP, you get it for WIndows XP Embedded. In other words, you are a phenomenally stupid moron regularly applying patches for the wrong OS to your system, hoping / assuming that changes made for a different version of the OS are safe and actually fix the vulnerability. It really takes the mystery of why you have to keep reinstalling (ROTFLMAO)
Don't even bother to come to school tomorrow. You have no hope of making it through the school year with anything better than a big F.
Which reminds me ... yes I could write fuck, but on Slashdot the word fuck is spelled fsck. If you weren't a Windows douchebag who doesn't belong here in the first place, you'd know why the adults use fsck rather than fuck when posting on Slashdot.
Now off you go ... and go fsck yourself.
