i cant open any microsoft updates websites in my xp os

a.s.girish, a couple of things come to mind. One's M$ itself. They have the annoying habit of resetting security level to 'high' which will block ANY website (not just M$) not specifically permitted. Next is a virus/trojan/worm. M$ is a frequent target. Run an AV scan to see. If that still doesn't help, you may have to go deeper. GO INTO SAFE MODE. Be aware that a virus and a Trojan are similar, but not the same. Many times, an AV detects one it can't clean, other times, it gets missed entirely. If you need to clean one, Superantispyware can do the job and you can get it free @: http://www.superantispyware.com/ among other places. They have a Vista compatible version if needed. If it turns out that you need to use it, be sure to update prior to running and disable 'restore' (restart after cleaning) so it doesn't get put back. They just released a new update recently and it changes all the time. Things are in a constant state of flux. The restore thing is critical. May not be your deal at all, but won't hurt anything to try. HTH. Ed in Texas.
