Just out of curiosity, when you search for Windows Features on the recent Insider Builds, does Windows Subsystem for Linux show a 2 after it, or no?

 

I just ran a plain-vanilla Windows 10 2004 Update, and it doesn't specify that the version was upgraded.

 

I had WSL1 enabled before the update.

Followup. On the release version of 2004, Turn Windows Features On and Off will not say whether you have version 1 or 2

 

You can verify the installed version of WSL in Powershell using:

wsl -l -v

 

If you had Version 1 before running the 2004 Feature Update, you will stay on Version 1

 

To upgrade from WSL1 to WSL2 on Windows 10 version 2004 up:
Open PowerShell as admin and run:
  dism.exe /online /enable-feature /featurename:VirtualMachinePlatform /all /norestart
Restart computer
Restart again if prompted
Run in PowerShell:
  wsl --set-default-version 2
If it says kernel must be upgraded, install the update from:
 
  then, rerun:
    wsl --set-default-version 2
 
You can check the version for all running distros by:
  wsl -l -v
 
To change version of existing distro use:
  wsl --set-version <distribution name> <versionNumber>
 
Edit:
Even after performing the above steps, you may be greeted with the message:
Exporting the distribution failed.
bsdtar: (null)
 
And have to reinstall your distro.
 
LOL
 
Further Edit:
Reason for upgrade failure: Windows Defender blocked your Kali distro as a trojan
Add folder to exclusions list, and reperform upgrade
