I have run into a jam. I need to upgrade the Wireless Network drivers of 220 tablet PCs running windows 7 32-bit. The drivers from the manufacturer of the network cards (atheros) are unsigned, so I need to disabe digital driver signing in a way that is least disruptive to the users. Another problem with these drivers is that they are basically a bare driver with no EXE attached. I have that sorted out using Devcon to make this work.
I have seen some talk of using BCDedit and turning off driver signing, but as I understand it, that requires a reboot. Is there any other way of doing this?
