Couldn't hurt anything.
I'd do the official uninstall method through Control Panel, restart, then install them. If windows tries to update after the restart, I'd just click Skip or better yet disable automatic driver installation

Turn it back on after your done because if you ever plug in like a flash drive or printer or anything... you want it to automatically do it... but it can cause problems when you have your drivers ready to go and windows first wants to throw (god knows what) at it first.
