Clean Install of Windows 10 - What OEM Product Key to Use

I how downloaded my Windows 10 Professional x64 ISO using Microsoft's Media Creation Tool.  I created my boot media on USB.  Now that I am installing it, it is asking for a Product Key.  The Windows 7 Pro OA product key that is listed under the battery of my Dell Latitude E5530 is not working.

- I can skip the initial failure and install Windows 10 on the drive

- Once the OS has loaded and walking through the inital setup screens, I am prompted again

- Finally get logged in (just using local accounts, and not a Live Account) I try to activate again.

The product key fails with error code 0x004f050.  This is basically a "Key" not valid.  

So what do we do with this scenario?  Do I need a different key from Dell?  Do I need special OEM media from Dell to recognize the BIOS? 

I know this is early, just wasn't sure about what protocol we need to use to upgrade hardware or just do a fresh installation with Windows 10.

Thanks,

--Jay

Same problem here. Has Dell gotten around to test Windows 10?

RE: Clean Install of Windows 10 - What OEM Product Key to Use

   I asked a similar question and I will tell you what I have heard to date. You cannot Install Windows 10 from the boot media. To be more specific you can't boot the boot media and install it. You must upgrade it. Upgrade only. You have to have a legit Windows 7 or Windows 8 installation running and than put the media in and "upgrade".

   I think this is whack. I don't want to upgrade. Microsoft Updates have never worked. I want to boot from the media, wipe out my hard drive and install from ground zero. I was told I would have to purchase a copy of Windows 10 with a Product Key to do this. That this is not "upgrading" in the true sense and thus I need to purchase. I hope Microsoft didn't do something that stupid but only time will tell.....

I've sorted out Windows 10 on 2 other machines (not Dells) and they've been really straight forward. You do HAVE to do an upgrade from Win 7 or 8.1, however once that's done you can do a full format and reinstall (as long as the hardware isn't changed). The upgrading seems to be needed to link the old key with the new Windows 10 licence. I've done that twice already and both are 100% fresh installs now and fully activated.

However saying all that my Dell laptop is being a pain and when I run the installer it keeps asking for a product key when neither of the others did.

do the silly upgrade, make sure your copy is activated.  Use the media creation tool, select other PC, put it on a usb.  reboot making sure it boots from the usb.  You may have to hit F12 or delete on boot to select boot from usb.  the setup runs.  when you get the the part where it shows all your partitions, i had 6, delete them ALL.  hit next.  that is a CLEAN install

I forgot, skip anywhere that asks for a key, don't enter anything.  It will auto activate since you did the upgrade earlier.

your product key will not work directly like that, you need to reinstall win8 and do what is in my post above

You need to upgrade first to windows 10. Once upgraded, check activation status  If it's activated, you can do clean install. No need to enter product key when you do clean install, because the system will remember it (I think it's tied to hardware and microsoft account you're using). Just skip that step and windows will be activated. That worked for me.

Kinda like needing to replace tires on your car but first removing the worn tires then installing the original tires came with the car, then taking those off then finally installing the new tires. Totally efficient.

RE: Clean Install of Windows 10 - What OEM Product Key to Use

I have exactly the same question.  I just bought a refurb E6420 with 4G memory and Windows 7 Pro on it.  I bumped the memory to 8G and installed Windows 10 via the .iso download.  Now that Windows 10 is running I can't activate it, because of error code 0xC004C003, meaning "The activation server determined the specific product has been blocked."  Just like JYB3, I tried to use the product key under the battery.

Prior to installing Windows 10, I confirmed that my Windows 7 was genuine.  The information I have from Microsoft indicates that I should contact Dell.

RE: Clean Install of Windows 10 - What OEM Product Key to Use

According to Microsoft Activation Support hotline you would need to downgrade your Dell system back down Win 7 or 8 then do the upgrade since the OEM product key won't work for the clean install of Win 10. 

IF you were able to get beyond that and activate your Win 10 system on your Dell please let us know how you were able to do it. Thanks!
