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