Hi,

I have "Windows 11 Dev Edition" and I want to upgrade to "Windows 11 Final" keeping my programs, configuration and files, but the options are greyed out and only let me a clean install.

Is there any way to force enable keep my personal files programs and configuration?

Not to my knowledge. When you're in the Dev channel you have to start over(clean instillation) to move to the RTM/release preview version. MS warned us about this a bit ago and gave us a chance to move down from the dev to beta with no issues. Then the major split happened and now you can't move out of the dev without reinstalling Windows.

This is where having a system backup of 10 using Macrium or similar would have been advisable. Restore Win10 then upgrade to 11 with an in place upgrade to keep all your files and programs etc.

You are so correct. Without a backup you can run into huge issues.

The problem is that my Windows 10 is LTSC so the backup doesn't work either.

So, no one in this forum is capable of trick Windows to think it is in a previous version the program "setup.exe"?
Nope. You would have to change the version numbers embedded in hundreds, if not thousands of individual dll files.

It's a challenge, reverse engineering to setup.exe to find where it check the build Number, someone could do it

Why won't you listed to folks here?

It's NOT a simple matter of "reverse engineering" setup -- or anything even remotely like that.

It simply can not be done!

No. You can NEVER downgrade Windows to an earlier major build number - full stop. The problem is not in the .dlls or .exe files, the problem is that a newer build will have different registry settings with new or altered functions that the Setup for an earlier build is unaware of and has no idea how to migrate to an earlier build. Upgrading to a newer build is straightforward, it's Setup will be aware of all the registry changes needed to migrate any earlier build to its higher one.

The only way to go back to the 22000 build from a Dev build with a higher major build number like 22483 it to do a clean install.

    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 it was re-imaged back to 10 and was offered the upgrade in Windows Update on 20th October.

Well, before the official release of Windows 11 was out, I had installed the latest Insider's Preview in my unsupported Acer laptop (see my specs). I then downloaded the official ISO from Microsoft and proceeded to upgrade the Preview version to the official release. Since I had unsupported hardware, I loaded Setup (inside Windows so I could upgrade), but before proceeding I browsed to Setup Cache folder and deleted the file C:\$WINDOWS.~BT\Sources\appraiserres.dll Without this file Setup skipped any system compatibility checks and let my upgrade. All other updates from Windows Update install without any issue as they never check compatibility. You will need to do the same trick if you want to upgrade to a future build. Read all the hacks to install Windows 11 on unsupported computers in this thread: Let's run Windows 11 on an incompatible hardware

If I were you, I would download the official Windows 11 ISO from Microsoft's site: Download Windows 11 and try the above hack. You never know
