Error code: Wsl/ERROR_NOT_FOUND

Question

Windows installed the update KB5032339 and WSL 2.0.9.0, and since then, I can not access WSL.

The error was the one indicated in the title of the question. I cannot work, because all of my work depends on WSL and I need docker desktop, which also depends on WSL.

I searched everywhere; it seems that I am not the only one with this problem. I tried uninstalling WSL and installing an older version, but the problem remains.

How can I solve this, or is Microsoft going to release an update to fix this problem?

If you (like me) have this problem and find this thread, a short summary (not a Tutorial) so far ( as of 24.11.2023 ).

Please read the whole comment before trying any of it!

• Github Link to the problem is: https://github.com/microsoft/WSL/issues/10782
• Workaround:
  • Start WSL from an Elevated Terminal
  • So in "normal" language: Start your CMD/terminal with Admin Privileges then run the "WSL" command in this Terminal
• Manual Fix:
  • Type "regedit" in the Windows search and start Windows Registry Editor
  • Search and delete:
  • HKEY_LOCAL_MACHINE\SOFTWARE\Classes\PackagedCom\ClassIndex{A9B7A1B9-0671-405C-95F1-E0612CB4CE7E}
• Official Fix:
  • In theory, there Is a fix pushed and live (Version 2.0.11)
  • But for me and others "WLS --update" does not pick it up so you have to install it manually:
    • https://github.com/microsoft/WSL/releases/tag/2.0.11
    • You (probably (to 99%)) need wsl.2.0.11.0.x64.msi
