I performed a system reset not long ago, and now when I enter "wsl" on the command line, the system prompts "Cannot find registration class, Error code: Wsl/CallMsi/REGDB_E_CLASSNOTREG", which also prevents me from opening windows docker

    Hi，

    Please open "Turn Windows Features on or off" from the start menu, disable / enable the “Windows Subsystem for Linux” feature and see if the issue persists. Also give a try to the latest version of wsl.

    Best Regards,

    I've run into the same problem. After a windows reset, I'm unable to run wsl commands. User's image

    I've tried enabling and disabling the option multiple times with a restart in between, but it doesn't appear to make a difference.
