Speaking of Windows storage drivers, years ago, I managed to get Windows to boot and run entirely in RAM using some fairly obscure tools from the reboot.pro forums. I always wanted to have an immutable Windows system that I could manage like cattle. Unfortunately, setting up such a system was extremely complicated and a manual process. I am aware that Windows now has a driver called UWF that functions a bit like an overlay filesystem and can create ephemeral overlays, but it's not quite the same as booting and running in RAM. It's also only available in Enterprise unless you enable it via registry edits.

WinPE does that.

I did that for lulz few times in Linux when I didn't wanted to fuck up with some old server's boot when I was decommissioning it. Just make a big file in /dev/shm, add it via loopback to LVM and migrate system partition on it, then run shred on drives without the annoying messages kernel screams when it has its storage destroyed underneath

UWF does come in handy for things like thin clients from my experience.

You can boot Windows off a VHDX, which might serve your same needs. I'm running like this right now - it has a few quirks but works pretty well.

JFYI, nowadays (if you have enough RAM) we have a good driver that can load Windows both as a Ramdisk and as Filedisk (using a VHD or RAW image) booting via grub4dos or grub4EFI, SVBUS: http://reboot.pro/index.php?showtopic=21787 http://reboot.pro/index.php?showtopic=21787 https://sourceforge.net/projects/svbus/ https://sourceforge.net/projects/svbus/ http://mistyprojects.co.uk/documents/SVBus/index.htm http://mistyprojects.co.uk/documents/SVBus/index.htm
