Back when 23H2 came out, I had two unsupported pcs where I had to manually add the enablement packages. Unfortunately, I no longer have those machines. I kind of miss experimenting with those old machines..

I fired up my old HP-ENVY desktop with Win11 just to have something to experiment with. Right now it's running the current 25H2, build: 26200.9278. When the enablement package is officially released, I'll slap it on and see if it chokes. 🤣

It will be fine. If I remember correctly your HP Envy must have newer CPU than my 3rd generation main PC (2nd system specs). I run Windows 11 25H2 26200.9168 fine. Build 9278 could not install for some reason, but hopefully the next build coming this patch Tuesday will install. I will use the 26H2 Enablement Package to switch to 26H2 without checking compatibility and hopefully without issues.

    Legacy MBR installation, no TPM, no Secure Boot, no WDDM 2.0 graphics drivers, no SSE4.2, cannot get more unsupported ;) This is only my test laptop. I had installed Windows 11 here before upgrading my main PC. For my main PC I use everyday see my 2nd system specs.

24H2, 25H2, and 26H2 share a common set of system files. The one CU is applicable to all three. So yes, you will get the monthly CUs.

    UPDATE - 11 April 2026: due to lid hinges starting to break up this laptop has been retired from active duty. The OS with all software and files has been migrated to my System Seven in 'Other systems' to carry on as my general purpose 'main machine'.

    I've now clean installed 25H2 and used Garlin's scripts to update Secure Boot to CA 2023 and revoke the PCA 2011 certificates. It's new role is to test secure boot issues.

    Info for 2021-2026:
    fully 'Windows 11 ready' laptop. Windows 10 C: partition migrated from my old unsupported 'main machine' then upgraded to 11. A test migration ran Insider builds for 2 months. When 11 was released on 5th October 2021 it was re-imaged back to 10 and was offered the upgrade in Windows Update on 20th October. Windows Update offered the 22H2 Feature Update on 20th September 2022. It got the 23H2 Feature Update on 4th November 2023 through Windows Update, 24H2 on 3rd October 2024 through Windows Update by setting the Target Release Version for 24H2, and 25H2 on 30th September 2025 through Windows Update by setting the Target Release Version for 25H2.
