Question

Windows 11 Pro won't activate after clean reinstall — Error 0xC004F213 / 0x803F7001, OEM license, no product key found

I have a laptop (Lenovo V15) that came with a genuine, pre-activated Windows 11 Pro OEM license. Before reinstalling, I confirmed via Settings > System > Activation that it showed "Windows 11 Pro, Activated" with Product ID and the final few characters of my product key as well.

I recently had to do a clean reinstall of Windows (full format, fresh install from official Windows 11 Media Creation Tool ISO) after discovering malware on the device. After reinstalling and signing into my Microsoft account, Windows won't activate. I get:

Error 0xC004F213 — "Windows reported that no product key was found on your device"
Error 0x803F7001 when attempting slmgr -ato
Running Get-CimInstance -Query "select * from SoftwareLicensingService" | Select-Object OA3xOriginalProductKey in PowerShell returns empty/blank — no OEM key retrievable from firmware
The Activation Troubleshooter ("I changed hardware recently") reports no devices linked to my Microsoft account that can be used for reactivation
There's no physical COA sticker on the device
Phone/web activation (via slmgr /dti Installation ID) returns "our records do not recognize this as a valid product"

I have not changed any hardware — this is the same physical laptop the license was originally activated on. I'm hoping someone from Microsoft support can help me manually verify and restore activation using my Product ID, since all self-service options have been exhausted.

Happy to provide any additional diagnostic info (slmgr /dlv output, etc.) if needed.

You can also get ShowKeyPlus from the windows Store to see if that finds an embedded OEM licence.

Hello

If you have OEM license, especially if the OEM license was embedded in the motherboard, it should automatically reactivate. It shouldn't require troubleshooting step.

During clean install, did you recall whether it asked you to select edition, like Home vs. Pro? If OEM license is embedded in the motherboard, typically you wouldn't even run into this step.

Launch Powershell (note, it is not Command Prompt, but Powershell), and run this code to see if you have an OEM license on the motherboard. No need to share the license key if it returns any. Just tell me if it returns any.

No, it doesn't return anything. Would it be possible to retrieve the product key from the product ID and the last few characters then?

And yes, I was asked to choose the version that I wanted to install during the reinstall. I just got the laptop a few months ago and I don't recall needing to install Windows on it, so I just thought that since I can see Windows 11 Pro along with the product ID and product key, it would be OEM embedded

My product ID also has the suffix AAOEM

This means that the motherboard doesn't have the embedded OEM license, or there's motherboard issue that prevents it from being read. Your installation experience aligns too, since it asks you for edition, so it means it didn't read or couldn't find OEM license on board.

Unfortunately with the installation ID it cannot trace product key.

When you purchased the computer, did it come refurbished? If so, they would be using OEM-COA license, meaning, it is NOT embedded in the motherboard but entered manually. That would explain all of the behavior above. They should though, put the license sticker somewhere on the computer so you have the 25-digit key as you would need it when you reinstall.

Also, curious, what prompted the reinstall? Did you experience any issue? Just wondering if there's any motherboard related issue.
