To activate Win 11, what types of older license are good?

If I remember correctly Windows 7 Enterprise and Windows 7 Ultimate have almost the same features, the former is for Enterprises and the latter for enthusiast users that want the maximum features. That could explain why 7 Ultimate installed 11 Enterprise, but it is weird nevertheless. There is no need to reinstall, you can use the command prompt to install the generic Pro (or your Windows 7 Pro) key to go to Windows 11 Pro version and then activate using a valid Windows 7 or 8 or 10 Pro key.

Then by "rigmarole" I assume you mean simply change the product key to VK7JG-NPHTM-C97JM-9MPGT-3V66T to upgrade to Pro.

But, if you upgrade the installed Windows 10 Pro to Windows 11, it will upgrade to Windows 11 Pro.
Ho, ho, ho! It should be simple, but I found it was anything but. I have three desktops - the oldest had the free Pro update via the Win 7 Pro version I had previously and was no problem. The Win 7 came from the even earlier XP Pro and the desktop I bought in 2017 to replace one from 2008 and much earlier. That is still OK but very slow. I switch it on once a week and it updates itself to the latest Win 10 preview, features and updates without any problem.

As its slow, I decided to buy this one and it came with Win 10 Home from the manufacturer. After I had got used to it and installed the extra programmes I use, I went through the Upgrade to Pro via MS Store using the Settings page. After the install I got a message that Upgrade Failed and all changes would be removed to restore the original OS. MS Store service couldn't fix it and in the end made a case for free technical Support via Remote Access who took 4 hours to fix it. Months later a regular update changed my version to Enterprise and that was the end of successful Updates. 5 months later when the whole OS finally crashed Acer offered to put the whole install back to factory default for free and that worked, but left me with Home. My MS account showed the desktop as having Pro! But the System page showed Home. Eventually another remote session showed that the Store record apparently hadn't transferred to the digital license after the new install, so it was corrected and when the desktop woke up after a long nap, everything finally agreed that "ITS PRO"! Does that count as a rigmarole?

By the way, I started computing in the 1960s timesharing on a main frame Honeywell over a tie line using a teleprinter as the interface and punched tape as the programmes inputs. Since then I have worked my way through most OS iterations, including the small trial rollout of XP Pro. If you still don't believe me about the rigmarole, have a look on many forums for messages about systems getting changed to Enterprise when it should have been Pro. No shortage of those.

You could try to force the Windows 7/8/10 Pro key and then activate using the terminal. Right-click on the start button and open a Windows Terminal as Administrator. Then type this code:

Code:
slmgr.vbs /ipk xxxxx-xxxxx-xxxxx-xxxxx-xxxxx
slmgr.vbs /ato

The first line installs the key (where xxxxx... you type your actual key including the dashes) and the second activates it. Microsoft modified the code so it requires a valid key. The generic keys might not work. The same command can also be used to change from one version of Windows to another by typing the respective key.

I used my Window 8.1 Pro retail product key, and entering slmgr /dli from an admin command prompt shows Win 11 to be the Pro version retail channel. Even on a 12.5 year old PC that had an OEM copy of Windows 10 Pro installed on it and the Windows 11 Pro installed from the first "leaked" ISO are seen as Pro (retail channel) versions. All three installations use the same Microsoft account. Very strange, but I'm not going to complain.

I would have to disagree. I just activated Windows 11 Pro with a Windows 7 Pro OEM product key from a COA label. Once Windows 11 accepted the Windows 7 product key and activated, the installed product key changed to the generic OEM product key of NF6HC-QH89W-F8WYV-WWXV4-WFG6P.

I have a Pro key from old job I have been using for awhile. I was able to verify it using ShowKeyPlus utility. I am on W10 Dell Inspiron 7373. My MS acct shows the device is activated with Pro. But dont think any digital key is there.

slmgr /dli shows retail channel

I want to buy a new laptop that comes with W11 Home. How easy would it be to utilize my existing Pro key to get W11 Pro (or perhaps rollback to W10 Pro) on my new PC?
