Windows 10: Mouse will not stay locked to ANY fullscreen application. Need help

Whenever i play a game or watch a video in fullscreen mode my mouse can move across the screen and appear on my second monitor. This makes most games unplayable and is extremely frustrating, most fixes I've seen are specific to one game or involve setting a hotkey that will lock your mouse to a certain monitor. I would rather have it work in the same manor as before it had broken and am looking for any possible solution. This bug occurred 3 days after "Feature update Windows 10, version 21H2" and when I left my computer on all night long. would appreciate any help, thank you.IntelR CoreTM

"Scroll Inactive Window" does not respect Fullscreen application in multi-monitor config

when "Scroll Inactive Window" (settings > devices > mouse/touchpad > Scroll Inactive Window when I hover over them) is active it performs inconstantly with fullscreen applications, and the way the mouse performs otherwise with an application in Fullscreen
display mode. the feature works fine otherwise, but this side effect makes it frustrating.

for productivity this feels functional, and fluid. this mostly impacts things like games, but it still does not feel intended, or consisted with what Fullscreen is supposed to entail, or what things are actually constrained.

expected: in fullscreen mode the mouse is supposed to be completely constrained to the given screen/monitor, and all interactions of the mouse are expected to only interact with the window the mouse is locked to. for the most part this is why borderless-fullscreen
(or fullscreen borderless windowed mode) was implemented to have a program appear like fullscreen, but allow the mouse to behave like windowed mode.

issue: when running a fullscreen application like a game with "Scroll Inactive Window..." active, and using the mouse in the program, if the mouse would logically leave the fullscreen application "Scroll Inactive Window" will function even though any other
button of the mouse will do nothing, and with the logical position of the mouse being invisible to the user. this occurs with most any fullscreen application, and impacts multi monitor configurations.

example: having a program running in fullscreen mode (most prevalent in games), with a youtube video (could be a text document/webpage), and have the mouse logically leave the fullscreen application (if left monitor is non-primary then run mouse to the left)
then use scroll wheel. this is inconstant as clicks and secondary buttons do not function.

can this feature either respect fullscreen display mode, or maybe have a sub toggle for "use Fullscreen mouse lock"

 

Taskbar still visible in fullscreen mode

Let's try an attempt at resetting default computer settings by doing simple steps.

1) Right click on the Taskbar, and uncheck Lock the taskbar
2) Click-and-drag the Taskbar over to the left side of the screen, and let go of the mouse click, to set the Taskbar over there
3) Again, now click-and-drag the Taskbar from the left part of your screen right back down to the bottom
4) Right click on the Taskbar, and check Lock the taskbar

Try running full screen applications.

 

Mouse cursor not locked to crosshair in UWP applications

My mouse cursor isn't locked to my crosshair when I'm unpaused from Minecraft or other apps. I've tried reinstalling and resetting Minecraft, no good. Restarting my PC, no good.

Resetting UWP apps through Powershell seems to not work either;

Here's a short demonstration of the bug:

Such a mind boggling issue. Can't find a solution for this problem even on the internet.

Things I've tried that provided no solution:

• Resetting/Uninstalling Minecraft
• Reinstalling UWP apps to their defaults.
• Shutdown/Restarting my PC.
• Repairing my computer with SFC and DISM
• Repairing my PC with Windows Media Installation Tool (Upgrade PC Keep Files Option)
• Uninstalling/Reinstalling my mouse drivers.

I have tried recovering from a restore point and it seemed to fix the issue temporarily but the issue returned.
