Remove Wireless Projection Banner from Desktop screen

I've sent this to several teachers in my school, they say it works great.

I think re-naming the .dll could also be a good fix.

Control+Alt+Delete

Run Task Manager

Look for Windows Shell Experience Host process

Right click on it

End Task

Thank you Ivan for offering the best workaround. For those of you struggling to rename the file after taking ownership, I found that you may also need to grant your account Full Control to the file before you can rename it. Default access will be Read & Execute, and that will be insufficient to rename the file. 

I agree most of the posts in this thread - the Wireless Projection Experience bar is a nuisance and one of the most annoying new features added to Windows 10 1809. At a minimum, Microsoft could add an option to disable this feature under the gear icon. 

Unfortunately this forum is most likely not monitored by Microsoft but by volunteers who may or may not have the ability to help enact a change. For those of you that are vehemently opposed to this feature and would like Microsoft to make a change, it would be better to voice your opinion in the "Feedback Hub" application on your Windows 10 1809 device. Open "Feedback Hub," log in with your Microsoft Account, and either enter your feedback or vote up an existing entry. Search for "Wireless Display Bar Persists on Disconnect" as an example.

Simply annoying, more if you like to have the taskbar at the top of the screen. I like to have it there in my little Thinkpad.

I SOLVED it by renaming a file in c:\Windows\System32 named Windows.Internal.PlatformExtension.MiracastBannerExperience.dll

I've had to change the owner of the file from its Properties->Security->Advanced options->then at the top change the owner, next give permissions to Administrators users, and change the file extension to .old.

I've had to reboot for this lovely hack to take effect. I connected again to my Samsung wireless TV and no more stupid banner.

I don't know if this is a good advice but I've got rid of it.  I'm a simple user and won't be responsible if you burn your TV or Mars changes its orbit by renaming that file.

Please excuse my poor english.

MS please, why you call EXPERIENCE to things like this? If you add something to our work space, please let us disable it!! Or put it SMALLER.

Regards.

Man...MS seriously needs to pay you for solving this issue. Thank you for solving this issue.

You need to click to un-pin on the banner bar while you are still connected to get the bar to hide. Then use your notification sidebar to select "Project" then "Disconnect" to disconnect from your TV or projected screen. This order is the only way to get rid of the banner bar.

Dear Microsoft Wireless Display team,

Please add a configuration option to have ALL projection banner functions appear in the notification area and completely disable the banner.

As you can see from this thread, for many users the banner is an unwelcome and useless annoyance that spoils the user experience.

The notification area already provides the capability needed, why not use it!  Why clutter the user interface any more with superfluous toolbars?

Kind Regards,
