This specific keyword describes a multi-version installer, commonly known as an All-In-One (AIO) image. These are often custom-made ISO files that bundle multiple Windows versions and editions—like Windows 7, 10, and 11—into a single installation package for convenience.

How it works: If you install this Windows version on a computer that originally came with Windows pre-installed (like a Dell, HP, or Lenovo laptop), the installer reads the BIOS/UEFI license key embedded in the motherboard's chip.
The "Magic" Result: You do not need to type a product key. The setup detects the BIOS key automatically, selects the correct edition (Pro or Home), and activates itself instantly upon connecting to the internet.

To get the raw ESD file (for advanced deployment):
After step 5, cancel the ISO creation. Then navigate to %temp% and find the ~4GB *.esd file before it is deleted. That is the legitimate Windows 10 Pro 21H2 x64 en-US ESD.

Tampering: Because ESD files are encrypted, malicious actors can repack malware into an ISO after conversion. Always verify SHA-1 checksums against Microsoft’s official MSDN or Volume Licensing Service Center (VLSC) hashes.
Activation Status: OEM media requires a corresponding OEM SLP (System Locked Pre-installation) key in the BIOS. Without a matching HP/Dell/Lenovo BIOS marker, Windows will remain unactivated or enter a 30-day grace period.
Windows 7 EOL: Including Windows 7 in a "Pro" search is dangerous for security. Never connect a Windows 7 machine to the internet, even if the ESD is legitimate.
