Known Limitations (21H2 Specific)

• No longer officially supported by Microsoft (21H2 reached end of life June 2023). Security updates are disabled by default in Atlas builds—re-enable manually if used online.
• Windows Update is disabled by default; feature updates are blocked to prevent re-bloating.
• Anti-cheat compatibility is mixed: works with EAC and BattlEye in most cases, but some kernel-level anti-cheats may flag Atlas modifications.
• No Windows Store (though can be manually re-added via PowerShell).
• Some productivity features missing (Print Spooler off by default, BitLocker removed, etc.).
