You’re welcome for the quick response! If you’re thinking about installing Windows 10 by downloading it directly from Microsoft’s website and creating a USB installer, here’s what you need to know about the activation key.
When you install Windows 10 using the official Microsoft download and create a fresh installation, your original activation key from HP should still work, provided that it was a genuine, valid key and was linked to your device. Typically, the activation key saved in the registry or embedded in your device’s firmware (like with OEM keys from HP) will activate Windows after a clean install, especially if you’re using the same edition (e.g., Windows 10 Home or Pro).
However, if the key was tied to a specific version of HP’s pre-installed image or if your device originated with Windows 11, you might encounter issues. Sometimes, a digital license linked to your hardware allows Windows to activate automatically after an online check—no need to re-enter the key.
To verify your current activation status, you can open the Command Prompt and type slmgr /dli
. This will show if Windows recognizes a valid license for your device.
If activation doesn’t occur automatically after installation, you might need to input the original product key manually. You can find this key in the registry or on a sticker on your device (if available). If your key isn’t recognized, and you don’t have a valid license, you would need to purchase a new copy of Windows.
In summary, if your Windows was activated with an OEM key, and you’re installing the same version, chances are good it will activate without needing to buy a new license. Just ensure you’re using the correct edition, and check your activation status after installing.
