Thanks for the info Nozavi. Autopatcher for XP has saved me many hours of downloading updates on XP installs and in the past couple of months the new updates from MS are getting more and more. This program is a real timesaver.
As far as the last review from Aiman Tarek is concerned, it sounds like your boot files are corrupt or an update is conflicting with a file that is trying to boot. If you can, try booting into safe mode (F8 key while booting). If you can get there try a system restore from here to the date prior to your update. Don't quote me on this method as I always turn off system restore but I went into safe mode on my computer and tried the system restore and it seemed like it would work but in my case told me it was turned off. If system restore does not work from safe mode you might try running msconfig and turn off some startup items one by one to see if there is a conflict in some boot files. If you can't boot into safe mode you may have a reinstall ahead of you

Is February 2007 the end of autopatcher for Windows XP? It seems the Vista autopatcher is being kept current but not XP. Hope this will be updated soon as not everyone is going to Vista and this was such an excellant program for updating XP. Does anyone know of a similar program to Autopatcher that is up to date??
