So since the duplicate issue I was part of got 'resolved' by directing us to this one instead... Re-commenting my own issues that have not been resolved by the developers.
I have 2 monitors so this issue makes it pretty much impossible to play this version of the game. Full Screen does not solve the problem cause it's just an unbordered window. So when I look too far to the side my mouse trails off to my second monitor (or the task bar if I look down just like the OP).
I found a program last year that you can download called Cursor Lock which makes the windows 10 version of Minecraft playable.

Setup User Mode with the Lock set to Window Interior, designate whatever hot keys you wanna use for Locking/Unlocking, save it and then run the 'Start User Mode'. Problem solved.
I hope this information helps anyone else who is frustrated with this issue.

I have 2 monitors so this issue makes it pretty much impossible to play this version of the game, and I know I'm not the only one with a simple Google search. Full Screen does not solve the problem cause it's just an unbordered window. So when I look too far to the side my mouse trails off to my second monitor, which then makes it impossible to click on anything in game as it just clicks onto whatever my mouse is hovering over on my other screen (or the task bar as the OP experienced).
It isn't. This version of Minecraft (the java one still works great) is the only game that has this problem that I play and I solved it by the Cursor Lock I mentioned in my previous comment reposted from last year. Still, it would be great if I didn't have to use another program to do such a simple thing to make this playable with multiple monitors.
