It seems MS have removed the ability to disable the lockscreen using a registry edit. On my tablet, I now have to swipe screen to get to login prompt and after sleep.

If you set it to autologin using netplwiz or similar, it does not need to swiped at login, only after sleep.

Interesting on my laptop, it still works fine.

I can only assume this change is designed so they can advertise on lockscreen in time like the annoying Kindle Fire 7 Lockscreen (although I have disabled the ads).
