Enable Full Screen Experience on Windows

About

This script will take you through the steps required to enable the Full Screen Experience on Windows 11 25H2.

Currently, at the time of this repo's creation, 25H2 is only available through the Windows Insider Program through the "Dev" channel.

This script is me hacking together a batch script - which couldn't have been possible without some ChatGPT help.

My scripting knowledge stems from shell scripts, so taking on the Windows world was not easy.

That being said - I have used the script myself on my Lenovo Legion Go and it worked great. If there are any additions that would make this script even better, have at it! Submit a PR, and let's make this script even better if you find it useful!

   5. Sign into a Microsoft account if prompted
   6. Choose the "Dev" channel.
   7. Go through as many rounds of Windows Updates and reboots as required until the Windows 11 25H2 update is available to download and install.

Troubleshooting

While not much can be said on workarounds if these steps do not work, u/Gogsi123 has mentioned that possibly changing your device's display scaling could help enable the full screen experience.

Also keep in mind that this is beta software and there will most likely be issues ranging from minor bugs to hardware incompatibility, or even full system crashes.
