@Bree
Thanks for the link to the standalone version (I then uninstalled the store version)
---
Reviewing ShowKeyPlus I learned my Key's Edition is: "Win 10 RTM Professional OEM DM" (colon between M & D removed -twice- to avoid creating an emoji)

Not fully understanding how the (RTM & OEM DM) modifiers may affect my upgrade to W11 I'm checking with you for thoughts/comments.
Thanks again for sharing more of your knowledge in these matters! :cool:

The OEM:DM mean that yours is is an OEM key, supplied by the OEM when you bought the PC with Windows pre-installed. In practice as far as the upgrade goes it makes no difference whether it has an OEM or a Retail key, the purpose of the key was to get your PC a digital licence. That it has done, and the digital licence on the MS activation servers does not record whether it came from an OEM or Retail key.

PS: the :D to :D smiley substitution can be turned off by enclosing it in [plain]:D[/plain] BBCode tags.
That, and more useful tags, is to be found here: BB codes

    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.

    UPDATE - 11 April 2026: due to mechanical deterioration this PC 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.
