I can't even turn off Windows Defender, and I'm using Comodo. Even so, like I said, it says "You can turn this off temporarily, but if it's off for a while we'll turn it back on automatically." Don't forget to check under Privacy in your settings, even if you don't agree with my criticism of the other stuff, what's in there is fucking horrible. Can't even turn off sending information to Microsoft, only set it to "basic". The defaults choices are crazy, probably so they can force ads on you/sell your information. I've never really complained (meh, minor details that doesn't ruin the OS or experience) about Windows that I've used (3.11, 95, XP, 7), but I don't like this direction. Like I said before, my Music PC isn't connected, so I'll probably install a slaughtered, slimmed down version of 10.
