We own a business that provides IT services to small and medium sized businesses. I am also seeing Win 10 update issues with Lenovo laptops with AMD video and processors. If you have a desktop you can do as suggested and replace the video card. Just FYI my brand new high end desktop refused to boot after the last update. None of the recovery options worked. I had to reload the OS. I have a new laptop with Win 7 Pro and Surface with Win 8.1 so I have options, but I can understand your frustration.

I have had contact with both lenovo and AMD.
AMD has heard about the problem but has no answers!
I'm at the point of just praying that microsoft wont be limiting the number of times I will be able to do the rollbacks!
