For whatever reason, tonight whenever I would change mouse settings on my own laptop, MS in its infinite wisdom decided to change the same mouse settings on my wife's desktop. This has never happened before. I do have a login on the desktop, but this is strange behavior. Anyways, I went into my microsoft acocunt and unlinked/unsynced the desktop from my account. Still, the problem remains. My wife likes primary mouse button to be left, and I want mine right. So is there anything else I can do?
