About this tag
Docker Desktop on Windows can lead to significant disk space consumption due to dynamically expanding VHDX files used by WSL 2 and Hyper-V. These virtual disks grow as data is added but do not automatically shrink when data is removed, potentially causing a deceptively full C: drive. Users running Docker Desktop, WSL, or Hyper-V for extended periods may experience this bloat. Microsoft provides the compact vdisk command to reclaim unused space, and WindowsForum.com discussions offer practical steps for identifying and compacting oversized VHDX files. This topic is relevant for anyone managing Docker Desktop on Windows who needs to recover disk space without reinstalling or losing container data.

    WSL Containers Explained: Why Microsoft Says There’s No WSL 3 Yet
