Hi,

I am trying to figure out how to get rid of this bar in Excel, I upgraded to Win10 and it was not there in Win7!

Thanks! (image link on ImgBB below

Try clicking maximise window, icon near the top right though it's not showing in your image.

plot twist...it looks like it a space for a notification (Adxtaskpane apparently) which is opening in a seperate window as per below image:

Very strange obviously tried reboot, may have to reinstall or repair office!

Do you have any Add-ins installed?
