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.

    I am having the same issue with Windows 10 Build 1809 (OS build 17763.379) updated 3/14/2019

    It is not application specific. it happens on Windows File Explorer, Outlook, Internet Explorers (Edge, IE, Chrome, etc).

    If I move the application to another monitor (other than #1) everything works. If I start an application on another monitor in full screen state and then drag it to monitor #1, it fails. If I start an application on another monitor in less than full screen state and then drag it to monitor #1 it works. If I then maximize that application, it fails. 

    I am surprised that no one at Microsoft has seen this yet. This bug has been around a long time now!

    Not sure how many people are seeing this at the moment , Can any one advise if they've opened a job with Microsoft in regards to this issue?

    Seeing this issue for one of our users as well, I found removing the secondary screen and re-connecting it makes the issue go away for a time. 

    It does seem related to dual screen use and also affects most maximised windows on the defined primary display, affects all browsers.
