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.
@arielmt I just disable fast start. If I don't, my streams A/V desync at a frame per second until my mic and game audio are seconds off. Happens like clockwork and ONLY if I reboot with fast startup on.
Thing's bad evil magic and hardware doesn't expect whatever it does.
This tip brought to you by a help desk call about painfully slow Internet speed, yet the customer's router is freshly rebooted & the whole infrastructure up to the modem's LAN port tests good & speedy.
