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.

    Seriously, please stop offering people advice on anything related to their PC's. Killing DWM.exe will just cause more issues than most users want to even deal with beyond the resource drain of DWM.exe.

    Yes seriously!!!!

    I am in this thread since the beginning and just offering workarounds to people's with this issue!

    THE FIX MUST COME FROM MS!

    PS.: I have two users here: "popy_jules" and "TobiasDiendorfer"

    Resource leak is not really an issue when killing DWM.exe, i am just speaking of ME when i have used this workaround!

    It's just an normal process as any other which is handled by the kernel/OS, so leaking should not be a thing.

    And if there is any, just reboot -> solved!

    This workarolund was the first one which worked without an reboot for this issue.

    Now for me the key combination works.

    This can differ on your side with other hardware/driver setup.

    A other known workaround is to disable protected view on office program's but this i dont recommend!

    This opens a really big security hole.

    MS HAS TO FIX THIS!

    WOULD BE NICE WHEN THIS HAPPENS IN THIS DECADE :-)

    Perhaps if we could get someone to move this thread over to the Office support forums too it may be fixed quicker, as we have all established this behaviour occurs because of protected view in Office. How to we tag a forum admin in?
