    Glad it worked out. I already had my Nvidia drivers downloaded and ready. Just a small hiccup and MS thinking it knows best.

    Is there anything i have to do or optimize for installing on an SSD?

    I don't have those drives so I can't say for sure. I have 2 Samsung EVO drives and didn't do anything. Doesn't Intel have Intel Tool Box?

    Edit: Why yes it does!

    FWIW, I had the following experience when attempting to do a clean install post upgrade.

    1. Starting point was Windows 10 Pro build 240 from a week ago - probably should have let it be, but...

    2. Let the Media Creation Tool do the automated upgrade (again, of my existing Insider 240 build).

    3. Found that it left an undeletable Windows.old folder (DriverStore directories, etc.), so I decided to go the "clean" route.

    4. Used Media Creation Tool to download and generate a Windows 10 Pro ISO.

    5. Did a clean install, added some necessary chipset and wifi drivers, then attempted to activate. The activation dialog then reported that it couldn't proceed and that my key had been "blocked."

    6. Only recourse was to do a clean install of Windows 8.1 (using my Pro key, since my laptop's BIOS was configured for Home), then upgrade again - this time using the ISO image on a USB key (vs. another long download).

    I now have Windows 10 Pro up and running and activated - along with another undeletable Windows.old folder.

    I'm loathe to try another clean install. Everyone keeps saying it should work, especially on a machine that has already completed the upgrade process more than once. However, I can't help but worry that I'll end up in the same situation again and just have to repeat my 8.1-10 upgrade process. But that stubborn Windows.old folder really bothers me, so....hmmmm.

    UPDATE: Running ShowKey reveals that my OEM Key was for "Windows 8 RTM Core OEM: DM" while my Original Key was for "Windows 8.1 RTM Professional Retail." Interestingly, my Installed Key seems to be the same "-3V66T" key that everyone keeps talking about. Does any of this sound right? And was it a conflict between my OEM and Original keys (alone with trying to install from the Windows 10 Pro ISO) that caused my "clean" install attempt to fail?

    Curiouser and curiouser.... O.o

    Well truth be told, I did a clean install twice. I did it a second time after ran the secure erase on an SSD. Wanted a really clean install.

    Don't have windows.old Have you tried Windows Disk CleanUp?

    Yeah, Disk Cleanup was the first thing I tried. It took care of everything but a stubborn set of 4 driver files and their associated DriverStore folders. No matter what I do I can't get these deleted - this despite confirming that all 4 drivers are properly installed and being loaded from "C:\Windows\System32\Drivers" and not from the same structure under Windows.old.

    Very puzzling...

    Also, you mention doing a clean install. Was this an install of Windows 10 "Pro" or just the normal Windows 10 "Home" version? What version of Windows shipped with your PC?

    You can try from Admin Command Prompt:
    %SystemRoot%\System32\Cmd.exe /c Cleanmgr /sageset:35 & Cleanmgr /sagerun:35
    Select everything except setup Log File
