Do NOT install Microsoft KB2803676 & KB2795944. Installing these 2 updates will break your auto screen rotation.
I have experienced the same problem. I am glad you nailed down the specific updates causing the problem. Thanks,
Tee2nu and JarrodJ, I was hoping to get a little more information from you about the issue you are experiencing. Does the screen rotation start working again if you remove those updates? Is everything else up to date on the system (BIOS, drivers, other Windows updates)?
Any other information you could provide would help try to identify why these particular updates are causing this issue for you.
Had the same issue just today. Removing these two updates solve the problem. Thanks man!
