Windows 10: After some fullscreen games the hidden taskbar will not show up on mouse hover

It's a random thing that has been present in Windows for maybe 10 years, I think. You have to explicitly press Win button for taskbar to pop up or reboot the system to fix it.I wonder, if there is a easier solution to fix this.

Taskbar

Hi,

If in case that you're not seeing any search bar or box on your taskbar, this option can be hidden. You can have your search box appear on your taskbar by following these steps:

• Right-Click on the taskbar or Cortana.
  
• Hover your mouse over Cortana, then select Show search box.
  

Feel free to post back if you have other questions.

 

Taskbar in fullscreen

When I am in fullscreen watching youtube video or playing a game my taskbar hides as it should but when I go down with my mouse it appears again. So basically I can not play video games on the internet in fullscreen because everytime I want to look down
for example my taskbar pops up and it prevents me from doing so. Also when I am watching youtube video and want to exit fullscreen I go with my mouse to the bottom right corner I again my taskbar appears and I can not click the button.

 

Color Changes to mouse hover

I am running Win 10 Tech Evaluation and Win 7 in dual boot. That's fine.
But when it comes to personalizing win 10, the background colour of the hovering mouse is black,
so when it's hovered over black text, the text is obliterated.
How can I change the hovering mouse background colour?

Also, when in desktop, the RH toolbar's "speakers / headphone" and "new notification" icons do not show until the mouse is hovered.

And finally, how do I put the taskbar's "hidden Icons" visible on the taskbar.

Any help would much appreciated.
