This problem happens with all windows when maximized. 

When the window is maximized there is a bar at the top of the screen through which i can see my desktop. Its like that range that the window can maximize has been shortened.

Here is the link from reddit and this is the exact issue i am having. 

https://www.reddit.com/r/sysadmin/comments/8imjva/windows\_10\_multi\_monitor\_maximized\_window/

We did install all the latest and greatest patch that are available of today and nothing seems to work.

Any help please

In that Reddit thread, there is a suggestion that worked for me.

Right click desktop, go to Intel HD Graphics settings. Select Display and then choose the option Scale Full Screen. Make sure the option Override Application Settings has the checkbox marked.

Same annoying issue here on Windows 10 x64 1803 with all updates until now!

The issue appears on several apps (chrome, IE, eagle, ...) so it does'nt depends on the app.

My setup is: 2x HDMI/DVI 24" Monitors on an Radeon HD 5450. Internal Intel GPU is not used.

The issue just happend recently sind a few weeks.

I have found an workaround which helps at least for me:

 * Open Task Manager

 * Goto Tab Details

 * select dwm.exe and click "Kill Proccess"

dwm.exe will be closed and restarted automatically from windows and issue is gone.

Yeah i'll know, its a rather annoying workaround but the quickest for me until a real solution pops up.

    my situation has a AIO PC and an external HDMI monitor. One thing i noticed is that the video controls recognized the 2nd monitor as a TV. this i am sure would possibly throw the resolution off a bit. thanks for the fix as it did work! 

    also note this PC is fully updated with Intel, HP and Windows to all current as of 11-6-2019. my gut is that the (in my situation) Intel GPU/driver is detecting the display as a TV and not a monitor.

    This also seems to have fixed it for me. 

    But it has to be asked.. WHY.. is the tests not being done.. 

    And stop pushing updates out so close to xmas when it is a busy time of year for most people that work and don't have time to waste on debugging windows updates breaking things.. 

    Stop it already... no more forced updates..
