Install WSL on non-C drive

Open Powershell:

• Run Set-Location DriveLetter: where DriveLetter is the drive where WSL will be installed
• Then create a directory for WSL with New-Item WSL -Type Directory
• Now set location there with Set-Location .\WSL
• Now download the appx package with Invoke-WebRequest -Uri appx_package_url -OutFile Linux.appx -UseBasicParsing
• Now we will unpack appx with Copy-Item .\Linux.appx .\Linux2.appx and then Rename-Item .\Linux2.appx -Newname "Linux2.zip" and then Expand-Archive .\Linux2.zip
• Now Get-Childitem -Filter *.exe and you will find an .exe file named by the distro you downloaded. Run that to setup WSL you are done
