1. Download tools: ResourceHacker and mssstyleEditor, then unpack them
2. Download resources: Win8 theme for Win10, and then uppack it, we will need 'Windows 8 RP Themes for Windows 10\Theme\Themes For 10 Build 14393 Anniversary Update\Windows 8 RP\aero 8 RP.msstyle'.
3. Open it with ResourceHacker, export IMAGE 1055:0 and IMERSIVE 1:0.
4. Make a backup of the original aerolite.msstyles and make a copy of it to your working folder (arbitary)
5. Open it with ResourceHacker, Go to 'Action -> Add an Image or Other Binary Resource' or hit Ctrl+M to open the "Add Binary Resource" Dialog. Choose the menu image resource file that is going to be used, then change the "Resource Type" to IMAGE and resource name to be what ever available, in my case, 993.
6. Change the value of IMERSIVE 1:0, by importing the data from "aero 8 RP.msstyle"

scenario: you have a windows vm failing to boot with INACCESSIBLE_BOOT_DEVICE and changing the disk type to ide or something else causes another bsod. how to you get it to boot up again without a physical machine?

download the stable virtio drivers from here, in iso form: https://fedorapeople.org/groups/virt/virtio-win/direct-downloads/stable-virtio/virtio-win.iso

add the iso to your qemu/virt manager config as a cd/dvd drive

windows should send you to the recovery mode screen, but if it doesn't you might have to run a windows install iso to get to it.

Ubuntu 21.04 VM with GPU acceleration under Hyper-V...?

Modern versions of Windows support GPU paravirtualization in Hyper-V with normal consumer graphics cards. This is used e.g. for graphics acceleration in Windows Sandbox, as well as WSLg. In some cases, it may be useful to create a normal VM with GPU acceleration using this feature, but this is not officially supported. People already figured out how to do it with Windows guests though, so why not do the same with Linux? It should be easy given that WSLg is open source and reasonably well documented, right?

Well... not quite. I managed to get it to run... but not well.

How to do it?

1. Verify driver support
