    Windows 8.1 (with Bing!), Win 7 Pro X86, Win 10 64

    I seem to have succeeded!

    As promised, here is an update on my attempts at getting back a fully working version.
    Every suggestion that has been made in this thread I have tried and none of them worked insofar as my version still showed up as Windows 10 Enterprise and could not be activated.

    The last suggestion from Brink (message 73) seemed promising as it would get round one of my personal difficulties in contacting Microsoft. Sadly, none of the hopeful pages shown in the article's screenshots appeared on my screen! All the links I tried in the sequence described led me back to a webpage that asked me to choose a subject from four main headings that were obviously something to do with being an Enterprise user. (Premium Support and Developer were two.)

    Additionally I noticed that my computer seemed to be very much slower and the Task Manager showed heavy CPU activity even when I wasn't actively using programmes.
    So I went back to square one to try and analyse possible problems overall.

    Ran Memory Diagnostic after restart - reported that there were no problems.
    Ran System File Checker - reported that there were several corrupt files and repaired them. Ha, ha, I thought, the naughty upgrade did that so maybe all is clear. But no, still Enterprise and the Activate watermark on the screen.
    Checked graphics driver - showed that the latest update I had installed was no longer present, just an earlier version. Selected check online and it found the latest one again and installed it.
    End result, a computer that ran better but still couldn't be activated
    I put on my old Development Engineer hat and decided to try some lateral thinking (posh name for "suck it and see").

    Wondering why the idea in message 73 got me nowhere gave me a starting point. Maybe, I thought, I should make a stab in the dark and change the product key to 'downgrade' the OS to Pro. I went through that sequence but didn't use any of the Pro and Home keys I legitimately owned, but simply used the generic key for a retail Win 10 Pro that had earlier appeared in a message here.

    After some minutes of activity, bingo, the System page stopped showing Enterprise and changed to Windows 10 Pro. Eureka!
    Even better, after a few more minutes the message appeared, Windows is activated.

    That was 3 days ago, and I still have a Genuine Pro installation correctly activated. Even better, again trying the idea in message 73 the next day got all the pages the screenshots shown in the article, although only after the next restart. So now even that MS system agrees that I no longer am an Enterprise user. A few hours ago I looked up the comparison of features on Home and Pro - now I do have the few extra features in Pro to select if I want them.

    Conclusion - as I have written before, I would suggest to MS that their Upgrade procedure needs to inform the user if there is a problem with the product key entered, and STOP the process right there, before any damage is done. Back and Cancel options should also be added. It is dishonest to allow a customers system to be compromised when a simple check could be added. Particularly as the only way back at the moment is a complete reinstall of OS and programmes. Maybe the Insiders amongst us could get that idea discussed?

    Hopefully, my upgraded OS is locked into place and I won't have any more trouble. Though I have this forum to rely on if I do!


    PS Even better, my main reason for bothering to upgrade to Pro was that JNLP files would not work in IE11 as the necessary security option is not available in Home. With Pro, now it is, and the JNLP files run!
