Prefer this fork only if its compose/defaults changes match your exact deployment needs; otherwise upstream is the better default because it is far more current and substantially more maintained.
Choose this fork if you want a near-upstream Windows container setup with minor Compose customization and you are comfortable absorbing upstream maintenance gaps. Choose upstream if you want the freshest fixes and broadest support surface.
Jackthegr8at/kasm-qemu-dockur
stale
significant_divergence
Choose this fork if you want a Kasm-focused, heavily prebuilt environment with lots of bundled desktop tooling. Avoid it if you want the current upstream Windows container experience, because this fork is substantially divergent and materially behind upstream.
trycua/windows-local
slowing
significant_divergence
Choose this fork if you want a narrower, more opinionated local Windows container with multi-arch support. Prefer upstream if you need the full version matrix, turnkey ISO-based setup, or the broader deployment options that dockur/windows documents and maintains.
thatboyo/windowsVM
stale
significant_divergence
Choose this fork only if you specifically want its compose-file customization and do not need current upstream fixes. For most users, upstream is the better default because it is much more active and materially ahead.
nerdy-tech-com-gitub/windows
stale
significant_divergence
Prefer upstream unless you specifically need a frozen copy; this fork does not add capabilities and is materially behind current upstream maintenance.
Prefer upstream unless you specifically need this older pinned snapshot. The fork adds no visible features and is 113 commits behind, so it is mainly useful as a starting point for custom work rather than a better end-user distribution.
arcsource/dockur-windows
stale
significant_divergence
Prefer this fork if you need extra compatibility and version coverage more than freshness. Prefer upstream if you want the most actively maintained and currently validated Windows-in-Docker experience.
Prefer upstream for a stable, current Windows-in-Docker setup. Prefer this fork only if you specifically need its legacy-compatibility and customization changes and are willing to accept slower maintenance and likely missing upstream fixes.
