Hi, i have a W7 laptop that crashes after applying windows updates. On reboot it gets to 30% and then restarts and crashes. I have to then select repair then it all works again. I have tried repairing the install but it fails as soon as you apply windows updates again. it is on a MACBook Air all latest firmware updates etc. I am using bootcamp to get into windows and it has been fine until about 7/8 days ago.
