I did not understand What Polak said, He did IM me and say that He could not update SP2 using Autoupdate. In my earlier posting I was asking him if he was able to update SP2 or updated SP2 was preventing him from using Avast. Its got nothing to do with Avast.
Technical: Polak doesnot have Avast working on his computer yet!
Polak go to Microsoft site and download SP2 which is like 275 MBytes. Thats what Idid.
