Why Windows 11 Installs as Home on Some Laptops and Pro on Others

I downloaded Windows 11 from Microsoft, but when I install it on different laptops, it installs as Windows 11 Home on some devices and Windows 11 Pro on others. Why does this happen?

The Windows version and license are embedded in most laptops

You could take a look at this post of mine, for some idea on how to bypass the embedded info:


Also, if you use Media Creation Tool to download your ISO, make sure to uncheck "Use the recommended options for this PC" But you'll still need to manipulate the ei.cfg file.
I think there is another way, but I don't know it.

Each device has an underlying license key stored in its UEFI bios (as it came from the factory). A windows install usb drive will automatically install the version of Windows that the license key is for.
OOPS. Sorry @antspants, your answer was not there when I started this post.

You need to create a new file on the USB drive (using Notepad).

Copy this text to "E:\sources\EI.cfg", assuming E: is the Windows USB drive.

Without this file, Setup will default to installing the same Windows edition (Home/Pro) that matches your product key in BIOS, or if Setup finds an existing Windows folder on the system drive. By adding EI.cfg, Setup will allow you to select any edition to install.

Great question! As others mentioned, it comes down to the product key embedded in your laptop's UEFI/BIOS firmware — this is called the OEM Activation key (OA3).
Here's how it works:
1. OEM laptops come with a Windows license baked into the firmware at the factory. When you install Windows from a generic ISO (like the one from Microsoft's website), the installer reads this embedded key and automatically selects the matching edition — Home or Pro.
2. Consumer-grade laptops (HP Pavilion, Dell Inspiron, Lenovo IdeaPad, etc.) almost always have a Home key embedded, since manufacturers pay less for Home licenses.
3. Business-class laptops (HP EliteBook, Dell Latitude, Lenovo ThinkPad, etc.) typically come with a Pro key, since enterprise customers need features like BitLocker, Remote Desktop, and Group Policy.
If you want to check what key is embedded in any laptop before installing, open an elevated Command Prompt and run:
wmic path SoftwareLicensingService get OA3xOriginalProductKey
If it returns a key, that's what Windows will use during installation. If it's blank, the installer will ask you to enter a key manually.
And yes — if you have a Home key embedded but want Pro, you can always upgrade by entering a Pro product key in Settings > System > Activation > Change product key. No reinstall needed.
