Windows tip:
Is your PC doing weird things? Things so weird & frustrating that no one else on the Internet has ever written about it? Never disabled Fast Startup? Don't even know what Fast Startup is? Here's the quick fix:
Restart Windows. Don't use "shut down," don't use "turn off," don't use the power button. Those aren't true Windows restarts.
Start -> power button icon -> Restart
Do that once a month or so, even if you turn it on and off daily, & half the weird things go away.
