  3. Check if your current build number is lower than the fixed version for your release: Windows 10 1507 requires 10.0.10240.20526, Windows 10 1607 requires 10.0.14393.6796, Windows 10 1809 requires 10.0.17763.5576, Windows 10 21h2 requires 10.0.19044.4170, Windows 10 22h2 requires 10.0.19045.4170, Windows 11 21h2 requires 10.0.22000.2836, Windows 11 22h2 requires 10.0.22621.3296, Windows 11 23h2 requ
  4. Open Windows Update (Settings > Update & Security > Windows Update) and install all recommended security updates, or manually download the specific update for CVE-2024-21433 from the Microsoft Update Catalog at https://catalog.update.microsoft.com/search.aspx?q=CVE-2024-21433
  5. Restart the system after installing the update
  6. Verify the installed build meets or exceeds the fixed version for your Windows release
Caveat Standard Windows security update - minimal risk; ensure backups and test in non-production environment first if possible
