OK, found it at last. Don't bother doing what's shown in the video, it's a scam and it never works.

The actual variable you have to add has to be named "PlatformAoAcOverride" (to be created in the same place indicated in the video, same DWORD value = 0). Don't forget to reboot. Also works on Windows 11.

I could finally stop that f@#king netwok card from disconnecting my customers from their server every time the computer turned its screen off. You're welcome. And thanks Microsoft for being such assholes, issuing an update to purposedly remove the most important setting.

I exhausted almost all options.. NOTHING HELPED... Finally this simple trick did the magic. Reset the network adapter (update from your existing drivers in your laptop / PC) and hold the power key for 10 sec. Once shut down then restart again. Voila!!
