Maximize program across multiple monitors [duplicate]

Running Windows 10 with multiple monitors. I can maximize a program in a single monitor by clicking the little box in the top right, or by opening the menu in the program icon on the top left, or by using the window key + up arrow keyboard shortcut, or who knows how many other little shortcuts.

Is there a quick way to maximize a program or window across the whole desktop, including all connected/extended monitors? I'd prefer not to add any third-party software to do this.

I intend to use this mainly for two things: the occasional large spreadsheet, and for remote desktop connections when supporting users who also have multiple displays (mostly via the sccm client rather than the regular remote desktop program), so answers specific to those applications are helpful to me, as well.

Solution 1:

This is something I've researched heavily in the past. If you don't want to use third-party software, then I'm fairly certain the answer to your question is no; there is not an easy way to do this natively in Windows 10.

As you might imagine, there are many ways you can accomplish this with third party software. Below are a couple of easy examples, lifted from an older SU question.

If you're comfortable reading/writing scripts, the most lightweight way to do this is probably using something like autoit and a simple script. This SU answer to the same question but for Windows 7 has a script that will accomplish your goal, using the hotkey of your choosing.

Another answer to the same question references Dual Monitor Tools, which I've used in the past, and has this functionality, as described in the answer.
