I understand these posts are common, so I’ll keep it short. When my laptop failed, I swapped out the Windows SSD for a new one in my upgraded gaming PC. I expected Windows to stop working and couldn’t reactivate because it was an OEM key. About a year later, I added a new GPU and bought a Windows 10 Pro license, then changed the key in the Key Changer. It updated to Windows 10 Pro but still won’t activate. Is it because my installation ID is still OEM or do I need to contact support again? I’ve tried phone activation via the website, but they said I used it on too many devices. The error code is 0xC004C008. Could it mean I no longer have any activations left? Any advice would be appreciated—I’d appreciate help, even though it’s a bit frustrating to seek help online.
Typically, OEM Windows licenses included with laptops are linked to the device’s motherboard. When you replace that hardware, the license becomes unusable unless it was never tied to a specific system. Regarding a Windows 10 Pro license that doesn’t activate properly, it’s not uncommon—especially in grey market situations. Sometimes it works because it wasn’t previously bound to any hardware, but this is risky and not recommended. The main drawbacks are the watermark display and the inability to change wallpapers.
Thank you for the information. The key came from a German site called lizengo, which was presented as trustworthy by overclocker derbauer. Their service appeared genuine. At 40€, it wasn’t the cheapest option compared to some other sites. My issue is that my key has changed—something is visible in the settings, yet I’m on 10 Pro and still can’t activate it.
€40 remains a low price when comparing genuine or OEM costs. Format the drive fully and then turn it on. If it continues this behavior with a new key, the key may be faulty. Also, keep in mind that any MS-linked key could lead to problems.
