I usually have my G15 keyboard set to disable the windows key but....
Watch out for ( windows + E ) combination normally used to bring up Explorer.

If you use that to bring up Explorer and if you time right it sets your whole team on a run away straf right, they won't stop until you hit E again.
if you press other keys like the arrow keys they stop the straf but restart it as soon you let up on those keys. only pressing E again will you gain control back.
