There are a lot of issues with this update. Most significantly IMO are the "improvements" to the task bar search that essentially break it. You know when you open up the start menu, type what you want, it finds things on your computer, and you pick them? They broke it. There are registry hacks to disable the "new" search that restore it, but apparently there are other issues as well. It really screwed up my laptop. Fortunately it failed to install on my desktop, which turned out to be a blessing in disguise.
MS really needs to get their heads out of their asses and work on their QA game if they are going to keep forcing "more better features" on people that haven't asked for them. And stop trying to push everything onto the damn cloud. I don't need a Microsoft server to find the remote desktop shortcut on my own damn machine.
In before "it's working fine on my computer". Great. You win 0.5 Internets. Go buy something nice.
