Anyone have any clue why automatic updates kills my hive and sends me to startup repair hell? I reverted back to W7 on my laptop (fresh jnstall) so I could use my copy of 8.1 on my new build. Now, when the stupid thing installs updates, it bricks the boot and throws me into startup repair incessantly. I tried rebuilding the hive using copied files from RegBack...but no joy. Any clues?
