F10 save and restart. Now shutdown. Power up again, enter BIOS and re-enable TB. F10 to save and restart. Allow windows to boot. Results?
If you see the updater utility again, its what's causing the loop. See if you can uninstall it from Programs and Features and repeat all the steps above. Once you are back, try installing TB using the update utility again.
