WSL takes too much space ?

If you notice your WSL2 is taking too much space even after some clean, here's how you can compact your WSL2 virtual disk on windows (If you're having trouble with automatic, just doit manually)

When this issue will be fixed this part will be useless.

Use wslcompact. If wslcompact did nothing, you can try the following script to compact vdisk:

Automatic

Invoke-WebRequest -Uri "https://gist.githubusercontent.com/kipavy/fb858118c2b373369741ac084c6c3d45/raw/7598671681ec3513d9c27931d9730f57639f1436/compact-wsl2.ps1" -OutFile "$env:TEMP\compact-wsl2.ps1"; powershell -ExecutionPolicy Bypass -File "$env:TEMP\compact-wsl2.ps1"
