As of recent updates that I installed today, the task bar no longer appears when I move my mouse to the bottom of my screen if I have a fullscreen window open.
The taskbar is otherwise normal, and I can set it to not automatically hide or open it with the windows button on my keyboard, but I don't want to have to use either of these.
Edit 30th October: A recent windows update seems to have resolved this issue. I didn't realise for a few days, as I'd been working with the "automatically hide taskbar" option turned off.
Edit 1st November: I updated windows again last night, and the problem is back.
Attempting to restart windows explorer now also changes the autohide setting to "off", so now I'm stuck with a taskbar that won't hide OR unhide properly.
I am not happy.
Windows, how hard is it to just make taskbar settings do what they're supposed to?
Edit 22nd March: The problem randomly resolved itself for about 5 minutes. It then reappeared when I started typing this edit, then I went to the taskbar settings and saw that it was unlocked, locked it (I've tried messing around with the lock/unlock countless times before, with no success), and then the problem went away for good.
It looks like the problem has finally been fixed, but I'm half expecting the problem to just come back the next time I log on, considering how unreliable the taskbar has been up to this point.
Edit about 10 minutes later:
I immediately had issues as soon as I finished with my last comment.
Not only did the taskbar problem come back when I pressed the windows key, the edit I wrote about it wouldn't post.
Edit just after that:
So, the solution is this: Press the window key. Close the start menu, but keep the taskbar open. Move mouse off the taskbar so it starts to close, then move the mouse back onto the taskbar.
If the windows key is pressed without doing this, the problem returns.
WHY IS THIS SO CONVOLUTED???
Edit 23rd March:
And now that temporary fix has stopped working, just as randomly as it popped up.
