WSL users struggle to manage virtual disk space
Windows developers using WSL 2 can delete files inside a distro without recovering the corresponding space on the host, because the virtual disk may remain inflated until it is manually prepared and compacted. They also face difficulty expanding the distro disk for space-intensive builds, while some cleanup workarounds risk deleting Docker data. A small Windows utility could automate common disk-maintenance steps, though it would not address the separate multi-user installation or distro-renaming requests in the cluster.
For windows developers using WSL 2. Mentioned from Dec 2019 to Apr 2026 on GitHub.

Even after large amounts of data are deleted inside the distro, the host-side .vhdx can remain heavily inflated until the user manually compacts it
When I did this, it seemed like I first had to run sudo fstrim / in WSL to get a significant saving (14GB reclaimed with 8GB in use). A periodic background task that did this is really needed (and even better if it could be done online, of course)
