Windows 10: Maximize window hotkey does not work when program windows touch two sides of the screen at once

I often use the windows key + up and windows key + down shortcuts to maximize and minimize windows, but I've been noticing that if I have a window that is touching two sides of the screen left and bottom, top and left, etc. the windows key + up hotkey stops working. If I move the window away from the sides it works, but if I put it back it stops again. This is frustrating since I do not like having unused gaps on my screen and it shrinks the amount of space I have to work with in windows. I know this is a Windows problem because the same issue happens on my older desktop. I booted it up to c

touch screen only works on one side of screen

* Merged

* Original title: touchscreen works on right side of screen but not on left side. this isnt the first time this has happened. what do i do.

touchscreen works fine one minute. the next time i get on the computer it only works on one side of screen. right side works to touch and left side doesnt. In device manager I noticed that it has the touchscreen - normally it has only one listed, now it
has the HID touchscreen and also it has the same listed with a screen 1 and a 3rd listed as well as screen 2. I havent done any updates or anything to cause this. This isnt the first time it has happened. How do i get it back to working on the complete screen

 

Blank area at top of some programs when displayed in Maximized mode

I asked this question back on July 2020, but have updated it and am reposting in hopes that someone knows a solution. Others are experiencing the same problem.

The problem manifests itself as a blank area at the top of a maximized window. It occurs

• Only for certain programs (Notepad, Intel Graphics, Thunderbird, Firefox, Macro Exchange Pro32, VLC Media Player, Irfanview)
• Not for other programs (Word, Excel, Outlook, Powerpoint, Notepad++, PDFXchange Editor, Jarte, Mathcad, Visual Studio, Macrium Reflect)
• Only when the window is displayed in Maximized mode on whichever monitor is designated as primary on a dual-monitor system

When it occurs, clicking on the program's menu items does nothing, and if, for example, the X at the top right of the screen is clicked, it closes not the affected program, but rather any program underneath it.

The only way I've found to cure the problem temporarily is to reboot the computer. How long it takes before the problem recurs is variable. For example, I was free of the problem for over a month until 2 days ago. Now it's occurred 3 times in the span of 2 days.

I've seen various suggestions for curing the problem, but none have worked. For example, one person suggested using Task Manager to "end task" of dwm.exe. This works for an already-opened program, but if the program is closed and reopened the problem comes back.

This problem has been plaguing me (and others with dual monitors) for over a year. Any suggestions?
