No you can not remove the update, windows 8.1 has 2 separate sections, one is automatic updates, even with that completely disabled, it still updates drivers, you need to turn off "automatic driver updates" and that only has on or off, no other options, win 8.1 is another step in "protecting" users from themselves and taking away even more control as they seem to do in every new version of windows. I have tried the manufacturers drivers, same problem, seems as soon as a driver is certified as win 8.1 it no longer works with my router, I cant even install windows 7 as there are not all drivers available for the laptop hardware that are win 7 compatible, only win 8+. i think i will just have to suffer with my current setup until i get a new router.
At the moment when I want to install something new, for example, a printer, I have to download updated / new hardware driver, disconnect from all networks, turn on driver updating (you cant even manually install a driver if it is off), install new driver, turn on driver updating, and then reconnect to networks, a real pain in the butt, and the main problem doing it this way is that if there is an actual important driver update for one of my pieces of hardware, i will miss it, because if i am connected to a network and turn on automatic driver updates, it stops working about 2 mins later as it straight away installs new wifi driver
