1. How To Get Windows 10 Upgrade Without Waiting
2. Windows 10 Upgrade Without Serial Key Failed To Validate

My laptop (a Lenovo Flex 2 15) came preinstalled with Windows 8 Standard (with the serial key preinstalled into the BIOS), and I've since installed an SSD (a Samsung Evo 840 120GB) & upgraded to Windows 10.

When the laptop still had its hard drive, I upgraded it to Professional so I could use the resources provided by the domain on my homeserver; because of this, I can only use the Professional editions of Windows (Home can't join domains).

I bought Windows 10 Professional & completed a fresh-install (complete reinstallation) of Windows, only that it installed Windows 10 Home instead of Professional. I'm guessing this is due to the Windows 8 Standard Edition serial key preinstalled in the BIOS.

I then downloaded an All-In-One ISO image of Windows 10 from MSDN (of which I have limited access to), transferred the installer onto a USB stick, & reinstalled (a clean install again). However it's still installing Windows 10 Home.

I am able to get Windows 10 Professional to install if I disable UEFI & use Legacy instead, but I feel that this is stepping around the issue rather than resolving it.

Is it possible to have the Windows 10 installer ignore any serial keys preinstalled in the BIOS/UEFI? If so, how? If not, is using Legacy mode really the only way around this?

First of all, make sure you have a regular (single-architecture) Windows ISO. It seems you already have that covered.

Then, try this method:

1. Create a Setup USB drive

2. Create a file named PID.txt in the Sources directory, with the following contents:

3. Boot from this USB drive

First of all if you download Windows 10 using media creation tool it contains 3 editions: Pro, Home and Education. Windows automatically chooses one according to your serial key in BIOS or already installed Windows OS. You can force it to let you choose what you want to install by creating one file on your installation disc/USB drive.

Create ei.cfg file in sources directory on installation disc/USB drive, open it in any text editor (for example notepad) and paste this:

I have tried many suggestions to this including the ones listed in this questions an here but none of these answers was working for me with Windows 10 Anniversary Edition. I ended up doing the following to have a complete clean Windows 10 Pro installation with all components with a system that has an embedded UEFI Windows Home key:

How To Get Windows 10 Upgrade Without Waiting

1. Download the Windows Media Creation Tool. You could also create this from an ISO.
2. Use the tool to create a USB drive for the Windows 10 installation. Do not worry that you cannot select the Pro version in the Edition pull down.
3. Use the USB to wipe the drives and do a clean install of Windows 10
4. After the restart you may have a Windows 10 Home edition instead of Windows 10 Pro. If so, go into Settings --> System --> About --> Change product key or upgrade your edition of Windows
5. Enter in your Windows 10 Pro key
6. The system will update and after a restart Settings --> System --> About you will see Windows 10 Professional. If you are using a Microsoft Account you can also login via the web and see the device now displays Windows 10 Professional. However, if you reformat the machine again it will once more set itself up as Windows 10 Home instead of Windows 10 Pro (assuming it is finding this information from the embedded UEFI key).

At this point it appears you are all set. You might start working, try install Docker, etc. and think everything is fine. However, you will find that some important Windows 10 Pro components are missing. An easy way to see if this did not upgrade correctly is to search for 'Computer Management' and then you should see System Tools --> Local Users and Groups. If you do not see that item but your System --> About reports Windows 10 Professional something is not correct. Trying to restore these missing components with DSIM or other options did not work for me.
7. To fix this you need to Reset your PC. I know this is not what you want to do after just setting everything up but if you have tried using the PID.txt option suggested in another answer here by @daniel-b and it does not work for some reason this solution will solve this issue and it take less than an hour on a modern PC. You are working with a new empty installation now anyway so just go to Settings --> Update and Security --> Recovery --> and select Reset this PC. You do not need to select the option that says it will take hours and clean the drives.

8. After this is done it will be a new installation of Windows 10 again and you will need to setup your Wi-Fi, login with your Microsoft Account, setup a pin if desired, etc.

This time around, when you go to Settings --> System --> About you will see Windows 10 Pro from the start. You can also go to Computer Management --> System Tools and you will now be able to access your Local Users and Groups and you will have access to other features of Windows 10 Pro.

So, being the dummy I am, I installed Windows 10 Home over Windows 7 Pro. Right now, Windows 10 Home is unactivated because I can't use my 7 Pro key to activate 10's Home edition (I get error code: 0xc004f210 You are running Windows 10 Home. The product key you entered cannot be used to activate this edition.) I found that out through a call with Microsoft -- after we find out I'm trying to use a Pro key on a Home OS, I ask them how I can upgrade my current version of Windows 10 to pro. They tell me to clean install Windows and enter the Windows 7 Pro key at the beginning of the setup (I had initially skipped all of that and waited to activate after Windows 10 was installed)

So, I go to do a clean install off of the USB installer (really old version of Windows 10 that I had laying around from when I initially upgraded my laptop soon after Windows 10 was publicly released). I hit the 'enter your product key' right after I select my language (before I select which drive I want it on), and enter my Windows 7 Pro key, but get the 'This product key didn't work. Please check it and try again.' error.

My first thought is that I should probably download the latest version of the USB installer, and I'm downloading it right now, but that's going to take forever (> 1 day by the looks of it) with my slow internet connection. I'd also have to re-download all of the updates I finally got done downloading for Windows 10.

My question is: Is there some way I can upgrade from Windows 10 Home to Windows 10 Pro, without having to do a clean install, from the Windows store or something without entering the product key until after I upgrade? If I try to enter my 7 Pro key in the store for the 'I already purchased 10 Pro let me enter a key', I get the same error:0xc004f210 'You are running Windows 10 Home. The product key you entered cannot be used to activate this edition' I do when I try to activate Home with my 7 Pro key.

Edit: The Windows 10 Home edition I'm running right now is up-to-date using the current version 1511 build 10586.71

The reason you cannot use your Windows 7 Product key to activate a new installation of Windows 10 Pro is that this functionality was only added in Build 1511, November 2015, as mentioned on this page:

Starting with the November update, Windows 10 (Version 1511) can be activated using some Windows 7, Windows 8, and Windows 8.1 product keys. For more info, see the section Activating Windows 10 (Version 1511 or higher) using a Windows 7, Windows 8, or Windows 8.1 product key in this topic.

As such, you will need to use the latest build, as you have discovered and are now doing. The only way you will be able to upgrade to Windows 10 Pro without a clean install would be to first install the 1511 update and then use your Windows 7 Pro key.

I'm not sure which way would be quicker for you, but any build previous to 1511 won't accept that licence key.
