Windows switches to 2nd desktop after screen turns off and back on

Here's an interesting "bug" as it appears. My PC is set to turn off screen after 15 minutes (not sleep mode). If I have 2 desktops (in Task View) and I leave my computer on desktop 1 and screen turns off. When I come back and turn screen on (moving my mouse),
it always comes on on desktop 2. No matter what. This seems to be a bug. Or is it some weird setting?

Seriously, I don't know what creates this annoying bug. It's so annoying and happens at random. I can be watching my videos, reading an article and all of a sudden, my desktop is greyed out and the main running windows is duplicated or cloned out and every
thing that happens on that main windows shows on the other duplicated window including.. just watch this video and you'll see what I'm talking about. It's been happening for months between builds and not of them fix it. I just did a clean install as well so
its not that.

Looks like explorer has crashed and not restarted.
What happens if you relaunch it via the task manager?
(Press CTRL+SHifT +ESC together, File, Run new task, type
explorer
)

Or restart or log off/on (e.g. via CTRL + ALT + DEL).

Then check your Reliability History for an explorer crash and see if you can learn anything.
(just type
reliability
in Cortana's search bar and click on Reliability History and inspect the reports marked with an x).

 

Another thing you can check is Event Viewer to see if there are any explorer related issues.

 

Oh I found the problem I got file explorer confused with windows explorer so I went to task mgr to close it because it was lagging and then it happened

 

Ok.. File explorer is now the formal name (isn't it confusing) for explorer.exe 'explorer', contrasted with Internet explorer.
