Windows Defender is a two-sided thing: it has some useful features (incl., as you mention, now also coupled with the Windows Firewall) and some bad features (telemetry).

QuoteYou also didn't block unicast response which is mandatory to do in (Windows Defender) Firewall (it's "yes" by default). Outbound connections go on block all, allow only necessary stuff.

Surely I do not know everything... Please explain why unicast response should be deactivated!

QuoteI'm really not sure why are you against SU10++

You have described it as being useless because much is undone by Windows quickly. Not so with my manual settings: almost all of them have been permanent for years, except for some major Windows updates, especially during the early Windows 10 years or when fresh installing Windows 11 over Windows 10.

QuoteI mean Microsoft is still uncapable to fix KB5034441 in Windows 10 for 7 months at this point and if you want to manually fix it there's a high probability to brick your whole Win10 installation.

Indeed, I have also been suffering on my W10 PC.

Mich würde es interessiren ob auch eine onexgpu oder ein gpd g1 damit laufen würden

Would you mind test the CPU and GPU benchmark in the "Ultra Performance" setting? Your result seems conflict with the LaptopMedia (e.g. their 3D marr timespy graphic is 3701). Not sure which one to believe cause that's a huge difference (all the way from bad performance to top tier)

Antutu Wert wäre sinnvoll. sonst kann man die Leistung nicht einschätzen. 1Million+ sollte es schon sein um zukunftssicher zu sein.
