I also have this issue! I just started having it yesterday. I am too chicken to attempt a lot of the troubleshooting steps, even though I already tried a few. Thankfully the computer leads me into the desktop after a few minutes of reversing the changes, but I fear it may lead to worse problems! Can you simply just skip this update and wait for the next one?
Please Microsoft allow us to install the next update without installing this one! I rely on this computer for nearly everything.
