It seems to be an issue with spacedesk that after installation WSL2 does not start anymore throwing an error "Please enable the Virtual Machine Platform Windows feature and ensure virtualization is enabled in the BIOS. For information please visit https://aka.ms/wsl2-install".

There's a discussion on the spacedesk forum about the problem but no solution. https://www.spacedesk.net/forums/topic/wsl2-not-starting-after-spacedesk-installation/

  • Before installation WSL2 was working fine.
  • UEFI has virtualization enabled.
  • Virtual Machine Platform & Windows Subsystem for Linux is enabled in Windows features.
  • Trying turn off those features and on does not do anything.
  • Uninstalling spacedesk does not resolve the issue.

Can anyone help out to find the solution?

  • Uninstall all required features then reinstall all required feature rebooting after each step. Disable and then enable hardware virtualization (VT-x or AMD-V) depending on your hardware rebooting your machine between each step. What other software do you have installed that might be using the hardware virtualization capabilities?

  • @Ramhound thank you for your comment. I already tried several times to disable and enable Window features, turn off and on the Virtualization in the UEFI. I do have VirtualBox which by the way also stopped working throwing error: WHvCapabilityCodeHypervisorPresent is FALSE! Make sure you have enabled the 'Windows Hypervisor Platform' feature. (VERR_NEM_NOT_AVAILABLE). AMD-V is not available (VERR_SVM_NO_SVM). I have another computer where WSL and Vagrant both working fine together.

  • What version of Windows 10 are you running. What version of VirtualBox are you running. Only the current version of both Windows 10 and VirtualBox support a configuration where Hyper-V is also enabled. Have you tried my suggestion, exactly, the way I suggested? It's worth a try to uninstall ANY and ALL software that might be using the hardware virtualization x86 extension, then and only then, install the optional features for WSL2. Is hypervisorlaunchtype set to auto or off?

  • @Ramhound Windows 10 Pro 21H2, VirtualBox 6.1.18 r142142. hypervisorlaunchtype is set to auto. I followed your suggestions: 1. Turn off Windows features, reboot; 2. Turn off Virtualization in UEFI, reboot; 3. Turn on Virtualization in UEFI, reboot; 4. Turn on Virtual Machine Platform, reboot; 5. Turn on Windows Subsystem for Linux, reboot; Unfortunately, nothing helped.

  • Please verify that Core Isolation and You should also verify that Virtualization-based Security (VBS) are disabled.

One thing that you may want to try is the BIOS option called "Limit CPUID Maximum" or similar. Microsofts hypervisor has issues with this setting (and doesn't report it). Toggling it disables both WSL2 and Hyper-V on my system, even though all other virtualization works (including WSL1).
