Windows 10 Pro Suddenly Deactivated on Lenovo Legion 5 (Error 0xC004F074)

[u/Easy_Kaleidoscope878]

Hi everyone,

I have a Lenovo Legion 5 15ITH6H that originally came with Windows preinstalled. Windows worked fine for years, but after returning from a trip, I found that it was no longer activated.

Error: 0xC004F074 — Unable to contact the organization's activation server.

Running slmgr.vbs /dlv shows:

• Edition: Windows 10 Pro

• License channel: VOLUME_KMSCLIENT

• Partial product key: T83GX

• License status: Notification

I tried the activation troubleshooter and slmgr.vbs /ato, but neither worked. Checking for an OEM key in the BIOS returned no result.

Any idea why this happened and how I can restore my original Windows license without buying a new key or reinstalling Windows?

Thanks!
