IKEv2 is broken again. My second account cannot access Windows Security panel. Other than that, lots of cosmetic glitches like Umbra said.
Like Lockdown said, Microsoft doesn't seem to carry patches from the previous build over into the new build because a lot of the things that are broken AGAIN were broken before and then patched. Now they're broken again. Like is nobody keeping track of what needs to be in the next build? It almost feels like there are two different teams working on Windows and they are trying to figure out what the other one is doing.
