    I turned on the "Global C-States" option anyway, and so I don't have Modern Standby. Can anyone who also has a Gigabyte X570 Aorus Elite motherboard confirm that they also have Modern Standby?
    It's basically an Intel thing for the Z390 era and above, although some APUs from AMD might have it. Doubt it's available on a AMD DIY desktop. Also while it's fun to play with new toys, I don't think you really want it on a Windows 10 desktop PC, at least it's my personal opinion that I prefer rebooting and shutting down at night, instead of using a phone-like sleep where the PC remains connected to WiFi and does stuff like updates and the sort.

    At the beginning, I also doubted that there was this function on the stationers from AMD, but someone on Aorus Master managed to turn it on. It is a pity that he did not write or has a Z390 or X570 chipset (and here and here is Aorus Master) so maybe it is like you write and AMD desktops do not have it. On the other hand, when you write that this function works poorly, maybe it is good that I do not have it

    I don't think it's working poorly, I think it's not particularly fit for a desktop system like yours seem to be, considering the X570 boards are sold as the enthusiast line, not the power saving at all costs "browse the web and play solitaire" line.

    Plus, Windows 10 is not particularly stable, entering hibernation will write GBs to the SSD, the more the larger your RAM, new drivers at time require cold rebooting and get confused by the hibernate function, in short, PCs are not phones (yet) and they tend to function best with adequate care. You would also lose all the other power states like Sleep with S0/Modern Standby active.

    But yeah, it'd be fun to play for a day or two with a new feature, that's for sure, i would definitely enable mine for a few days if it was available, just out of curiosity, for the same reason I enable VBS and Memory Integrity, and then just returned to Kaspersky and turned them off. Toys are fun.

    I even turned on ErP in the BIOS, but that's not it either. Well, apparently I don't have Modern Standby. Let me ask you so. Firmware protection in the Core Isolation tab only works on the Intel CPU, or can it be enabled on AMD?

    Memory Integrity is basically a virtualization based security feature so it should be available on AMD too. Enabling HyperV (which VBS, Memory Integrity etc. will do) might shave a tiny bit of performance, which should be negligible is you have something like a 3900X. If you enable Memory Integrity HyperV will remain active all the time and you'll basically run your OS in a VM. Depending on your hardware, it might conflict with some drivers, for example on my setup it fails to turn on from the slider in the Defender UI because I have Steelseries' Engine for my keyboard+mouse combo, but it can be forced through the registry. Also it will likely conflict with older drivers, which is likely not the case for you, but on my FX8350 PC I have in another room, with an antique HD4850 card from 2008 in it, if I turn Memory Integrity on it will run the display in the Standard VGA mode like it has no driver.

    I wouldn't bother with it outside just fooling around to see what happens, which is pretty satisfying to do on new systems you build that will enable OS features and the sort, so just go ahead, do some benchmarks before and after and see how it impacts your performance, maybe even report back in the VBS topic:

    Here is a much easier way which basically does the same as mentioned in my previous post:
    1. Download and extract Attachment 252821
    2. Open a administrative command shell and enter:
    scewin /i /ms "Low Power S0 Idle Capability" /qv 0x01 /lang en-US
    3. Reboot and done.

    Edit:
    This also works with every other BIOS entry that is usually inaccessible on the regular UEFI setup.
    To get a full list of all commands:
    scewin /o /s nvram.txt /lang en-US

    I tried this and it certainly showed up as supported, but it worked erratically. Half the time it wouldn't stay in sleep. I expect the motherboard just doesn't fully support it.

    OK, but I'm not asking about memory integrity, but about firmware protection (the latter function from core isolation). I have memory integrity turned on, but the latter function is turned off and I cannot turn it on even through the registry

    You probably end enabled some additional stuff in Defender. On my Windows 10 Pro, Memory Integrity is the only setting in Core Isolation.

    I have a question. Is it possible for some driver not to handle the S0 state? The manufacturer of my motherboard claims that my motherboard's UEFI supports this power state, and whether or not it works may depend on the system, but also on the drivers (in the sense that the drivers can also prevent S0 from being turned on). The system was already reinstalled and it did not help to turn on S0

    I tried this on my Z390 and I got S0 Low Power Idle in the list of supported modes when I do "powercfg /a". However when I put the system to sleep all the fans (including CPU fan) keep spinning, but the display turns off. So it does not look like the system is fully sleeping. Was anyone able to fully enable modern standby using these instructions on Z390?
