Run all Windows maximied as WinSE, Shell-Windowing-ShowMaximized ?

I am interested in the option in ProductPolicy for Windows 11 SE, that makes all windows start maximized.
Option is called Shell-Windowing-ShowMaximized and is "1" only in SE.
I don't like SE (no one likes SE ), but on my phone I want to use arm64 version of Windows 11 and want all the windows run maximized, as it is done in SE by default. Without all the limitation - especially to Windows Store usage - on phone it is a must.

Is there a way to achieve all windows run maximies on Pro or LTSC without touching ProductPolicy?

 

Thanks! Please some more info, as the answer wasn't clear for me

Do you mean, I can modify policy .xrm-ms fille?
Or change ProductPolicy (offline), so that SPP won't revert it back?
I turned off a test VM, mounted VHDX, ran PPEditor 1.5, selected Load Offline registry and "use offline registry", found the setting, modified it to 1, saved registry, unloaded offlince registry, unmounted vhdx, booted. Setting is back to 0. SPP?

For glazewm, - I could't understand on GitHub what is it. How can I use it on my Windows 11 (arm64) to solve my task?

There is no PPIPro/Team with 26100 anymore, right?
Can I import strings from ProductPolicyOptions somewhere to override them? Doubt, as it explicitly says "0" in PPO.

And what exactly does glazewm? Some alternative Windows Manager?

 

Thanks.
I see a lot for x86/x64 but not for ARM64 Windows

 

OS would reboot each hour, right?
That doesn't work for me
