I would advise you to wait a little longer if you didn't update yet.
There are also many other issues, albeit small, like:
- resetting some settings (screensaver, logon screen, some video settings in nVidia control panel, monitor refresh rate, language input etc.)
- network icon not highlighted anymore in Action Centre when connected (you have to click one more time now to open a separate menu with your connections),
- Action Centre tray icon is at the right of the clock and it's not re/movable,
- Windows Defender is always ON and does scheduled auto-scans that you can't stop and what's crazy is that it does these scans even if you disable it while installing a 3'rd party security solution
- start menu has all the shortcuts (recently added, most used, all programs) crumbed together in the left side (they say it was done to avoid one more click)
- Cortana enabled by default in supported regions with no easy way to disable
- in my case svchost.exe service was left eating high amount of CPU time, so I had to hunt down the culprit (you know that "Service Host: Local System" is home for many services and you don't get separate info on them from M$); turns out windows update service hanged during the update process and it's still not working (maybe that's a good thing?); the solution for high CPU usage was to stop wuauserv, cryptSvc, bits, msiserver services, rename/remove SoftwareDistribution and Catroot2 folders and then restart those services.
- I'm sure there are more, but I can't think straight right now and don't remember them...
P.S. I didn't get Skype auto-install/auto-login problem, thank God!
