Installed windows 8.1 preview last night and after installing i get stuck at the lock screen, cant click or punch keys to log in. Since the powers that be decided to change how you boot into safe mode is my only option to format?
im currently using an apple keyboard hooked up via usb with a logitech t650 wireless track pad. i have a wireless microsoft mouse and a wired razor gaming mouse ive tried all of them, don't have another keyboard though. my pc is a home build with a sandy bridge i5 and a asus p8z77-v pro thunderbolt mobo.
The issue is most likely that it's an incompatible Apple keyboard and not a Windows keyboard. Do you have a friend that you could borrow a Windows Keyboard from to test with? If not, then you can usually pickup a plain Windows keyboard pretty cheap.
Be sure to restart the PC when switching a mouse or keyboard for the system to recognize it.
