Upgrading unsupported Win11 machines from 24H2 to 25H2 without full ISO reinstall

Upgrade unsupported Windows 11 machines from 24H2 to 25H2 without reinstalling the OS entirely from ISO

To upgrade, you do not need the full ISO to install 25H2. Because the update is in the form of an eKB, the update package only enables features already present in 24H2. So all you need is to install the update package and the update will be complete. Please note that these instructions are only for computers with x64 Intel/AMD CPUs because first, I do not have any hashes, and two, most ARM machines are supported anyways and the only ones not supported are typically VMs and you can find instructions elsewhere for those.

Instructions:

  1. Download the Intel/AMD update package from Pureinfotech page. These links lead to the official Microsoft Update Catalog page.
  2. Check the SHA512 hash of the package. It should be 91c5c513966131c12b5abc372c4311f4dcbc64606ac0011e10c38add69e721cace5c5935666fa498a08878302d1a0237fc21d4693b70c4ee2449f3f260dc25f2 .
  3. Double-click or somehow just open the file
  4. Agree to all prompts
  5. Allow the Windows local manual updater to reboot your computer
  6. Profit
