I just can't believe how many days have passed since MS released the November update which screwed so many PCs worldwide and they have done absolutely nothing to fix it. I've lost so much time and money that I decided to migrate to Linux.
People, I'm as unhappy with this as the rest of you, but an update of this magnitude can't be fixed overnight. It's been only about 2 weeks. It needs to be fixed, but also tested against an wide variety of environments (or do you want it to screw something else up along with fixing File Explorer?)
You don't need to go to an entirely different operating system. As mentioned earlier, you can simply roll back 1909. It wasn't so major that you lose any must have features. Here's an article on how to do the roll-back:

EDIT: yes, it's still a major screw-up in the first place.
