2. WSL vs WSL2?
The major difference between WSL and WSL2 is full support system call compatibility and increased file system performance.
According to Microsoft, WSL2 uses an actual full Linux kernel running on a managed VM (virtual Machine) with fast boot times.

- Once it done, you’ll be welcomed with the following details
Check whether your linux distro is running on WSL2.
These steps will let you know whether Ubuntu 20.4(in my case) is running on WSL2 or not.
Let the Ubuntu 20.04 app be running. Open cmd or powershell and enter the following command
wsl -l -v
- If you got something like this, Bravo🎉 your linux distro is running on WSL2.
- You’re free to set your linux distro to either WSL or WSL2 by using the following command
wsl --set-version <distribution name> <versionNumber>
<versionNumber>should be either 1 or 2.
