Real issue hit on a real run: dockur/windows warns about BTRFS storage but it's not idle -- on this host it boot-looped Windows Setup for hours (same log lines repeating forever, disk barely growing), a known bad combination for QEMU disk images on a copy-on-write filesystem. build_windows.sh now disables COW on storage/ itself (chattr +C, harmless no-op on non-btrfs or an already-populated dir from a prior run). README updated to reflect both real fixes now confirmed needed on this host (this one, plus the earlier SELinux :Z mount fix) instead of the original "written but never run" status.
