I have windows vista home premium installed and whenever there is an update available which is critical, windows automatically updates my system and in the process closes all the files I have kept open. By doing this it automatically force quits all the files and restarts the computer thus I have lost my work many times (when I am not around my computer)..some how even the autorecovery in applications like winword doesnt back up the files. This seems annoying and is there any way to prevent this from happening.
