After windows Vista installed kb890830 and kb978542 I noticed 4 problems so\nfar.\n1. MSN Service not available, error code: 800706b5. (This happened with\nprevious updates and I fixed the issue by doing a system restore to a\nprevious date.)\n2.When I started internet explorer (ver 8.0.6001.18904) I got a message my\ndefault search engine was corrupted by another program.\n3.I tried the usual system restore and found there were no restore points\navailable\n4. I had some unknown problem trying to log into this site. It kept giving a\nsite not available message.\nI am running windows vista home premium with sp2.\nI am using AVG free for my antivirus protection.(never had any other\ninstalled)\n\nAny help or advise would be much appreciated. Problems 1 and 2 above I have\nencountered on almost every windows update. Problems 3 and 4 are new for this\nupdate.
