Hello, I've been searching for an answer to this problem for some time and have found many threads realting to similar instances, but they all relate to older operating systems. I've seen this problem on several machines so far. A new MBP, imaged with Snow Leopard. I install bootcamp and load Windows 7/64 bit Enterprise edition. I install the previously downloaded Windows support drivers. I join the PC to the domain and reboot. After that, Windows requires ctrl+alt+del to log on. Ctrl+alt+del doesn't work, nor does addding the FN key to the mix. I can log in using a PC USB keyboard or using the on-screen kb, but both of those are less than elegant solutions. As near as I can tell, the problem is the del key. After the install of the windows drivers the del key is mapped as a backspace - Windows is looking for a forward delete. http://support.apple.com/kb/HT1220 This article states "Note: If you disable the Apple Keyboard Support driver in Windows, Windows will not recognize extended Function keys, nor the (Fn) key." I haven't purposely dispabled this driver - nor do I see it it there. Any ideas? Thanks!
