You are about to replace a motherboard, or you already did, and Windows has started saying it is not activated. That is not a mistake and it is not a scam message.
Your license was tied to the hardware you just removed. There is a two minute job that would have prevented it, and it is worth doing on every machine you own before you need it.
I read what this machine reports for its license before writing. It is activated, and the answer to the question that matters is not in any command I ran.
What a digital license is attached to
One phrase from Microsoft, and it explains the whole problem.
⚡ Microsoft states it in six words on its reactivation page: "the digital license associates itself with your device's hardware".
⭐ Not with you. With the machine. Change enough of it and the license no longer recognizes what it is looking at.
⚠️ A motherboard is the change that does it. Microsoft treats that as a new device. It is the commonest reason a working PC suddenly asks to be activated.
⛔ A drive, memory or a graphics card usually does not. It is the board that carries the identity. The watermark that appears when this goes wrong has its own page.
The two minute job that prevents it
Microsoft states the reason plainly.
⭐ Microsoft says: "Linking your Microsoft account with your digital license allows you to reactivate Windows using the Activation troubleshooter whenever you make a significant hardware change."
⚡ The route, in its words: "select the Start button, then select Settings > System > Activation", then "select Add an account".
⚠️ Do it now, while the machine works. The link has to exist before the change. Not after.
⛔ Afterwards is too late. That is the whole point of the sentence above. It is also why people find this page in a panic.
What this machine reports
Measured, and it is the ordinary case.
⭐ Windows here is licensed, on the OEM channel. The product key sits in the machine's own firmware, which is what a laptop that came with Windows looks like.
⚡ The account signed in here is a Microsoft account, not a local one. Windows reports its source as MicrosoftAccount when you ask it directly.
⚠️ And there the reading stops. Nothing I ran will say whether the license is actually linked to that account, because only the Activation page shows that.
⛔ One command in Terminal reads the license half of it:
Get-CimInstance SoftwareLicensingProduct -Filter "PartialProductKey is not null" | Select-Object Name, LicenseStatus, ProductKeyChannelIf it has already happened
Microsoft's own route, and the wording matters.
⚡ Open the Activation page in Settings and run the troubleshooter. It only appears when Windows is not activated.
⭐ Microsoft's instruction inside it: "Select I changed hardware on this device recently, then select Next."
⚠️ You sign in with the account that was linked. It then looks for a license attached to your old device.
⛔ If nothing was ever linked, that route has nothing to find. Microsoft says so in its own conditions, and at that point you are into contacting support or buying a key.
Firmware keys, and why they confuse people
It catches out anybody who has reinstalled Windows.
⭐ A machine that shipped with Windows usually has its key in the firmware. Reinstall on that same board and it activates itself, with no key typed at all.
⚡ That is why people think they have no license to worry about. They do, and it lives on the board.
⚠️ Replace the board and that key goes with it. The new board has its own, or none.
⛔ So a firmware key is not a substitute for linking your account. They protect against different things.
What counts as a significant change?
The ranking is ours, in order of how likely each one is to trigger it.
⚡ The motherboard, almost always. This is the one.
⭐ A processor swap on the same board, sometimes. It depends how much of the identity changes.
⚠️ Storage, memory, graphics and peripherals, almost never. Swapping a drive and reinstalling rarely deactivates anything.
⛔ And a repair that replaces the board under warranty counts too. Ask the repairer whether they transferred the license, because good ones do.
Do this on every machine now
Four minutes, and none of it is optional if you keep your PCs a long time.
⭐ Open Settings, System, Activation on each machine and check whether an account is linked.
⚡ Link one if not. A Microsoft account can be created for free and does not have to be your main email.
⚠️ Write down which account goes with which machine. Two PCs and two accounts is how people lose track.
⛔ And keep the machine's model and serial somewhere. If it ever changes hands, that record matters for other reasons too.
Status: license state read here on 28 August 2026, against Microsoft's own reactivation page. The linking state is not readable by command and is not claimed. ⛔ No product key, account name or device identifier is published, and nothing was changed.
Why does Windows say it is not activated after I changed hardware?
Because Microsoft ties a digital license to the hardware rather than to you, and a motherboard change reads as a new device. Its own wording is that the digital license associates itself with your device's hardware. Nothing has gone wrong and nothing has been stolen.
How do I link my Microsoft account to my Windows license?
Go to Settings, System, Activation and select Add an account, which is Microsoft's own route. Do it while the machine is working. Microsoft says linking the account is what allows you to reactivate through the troubleshooter after a significant hardware change.
Can I reactivate if I never linked an account?
Not through the troubleshooter, because it has nothing to look for. Microsoft's conditions assume the link existed before the change. At that point the route is contacting Microsoft support with your proof of purchase, or buying a key.
Does changing an SSD or adding memory deactivate Windows?
Usually not. Storage, memory, graphics cards and peripherals rarely trigger it. The motherboard is the component that carries the machine's identity, which is why a board swap or a warranty board replacement is the one to plan for.
The Short Version
- Microsoft ties the digital license to your hardware, not to you.
- A motherboard change reads as a new device and deactivates Windows.
- Linking a Microsoft account beforehand is what lets you reactivate.
- The route is Settings, System, Activation, Add an account.
- It has to be linked before the change, not after.
- No command reads whether a license is linked. Only Settings shows it.
- A key baked into the firmware goes with the board when it is replaced.
- Drives, memory and graphics cards almost never trigger this.
Where to Next
Open Settings, System, Activation on the machine you are reading this on. It takes ten seconds to see whether an account is linked.
If there is none, add one now while everything works. That single step is what this whole page is about.
Do the same on every other PC in the house, and write down which account goes with which machine.
If you have already changed the board and lost activation, run the troubleshooter and choose the option about changing hardware recently.
And if you have been through this with a repair shop replacing a board, tell me whether they transferred the license in the comments. The good ones do and nobody mentions it.
