Windows 11 Installer

Summary

Designed to upgrade Windows systems to the latest version. It can be used to:

• Upgrade Windows 10 to Windows 11
• Install Windows 11 feature updates (e.g., 21H2 → 22H2 → 23H2 → 24H2)

Supports multiple source types including HTTP/HTTPS URLs, local files, and network shares (UNC paths).

Notes:
• If the script is run without the NoReboot flag, it will automatically schedule itself to run again 30 minutes after the upgrade completes to perform validation.
• If no parameters are supplied, the machine will be upgraded to 24H2 by default.
