T450s Windows 10 Pro Activation Failed

2018-11-08, 0:34 AM

Hello,

I've been using my T450s for 3 years. All this time It's been running on a Windows 10 Pro. Today, suddenly I got a notification that the "Windows is not activated" with the error code: 0xC004C003. According to the Windows 10 troubleshoot, my laptop has a Windows 10 Home digital licence! I did my best to fix the problem but wasn't successful. What should I do now?

Thanks in advance.

Solved! See the solution

I would try calling Microsoft volume license activation.

That may NOT be the most correct number to call, but if not hopefully they can re-direct you if needed.

Perhaps you will get  better answer, if not, give this a go!

Currently I do not work for, nor do I speak for either Lenovo or IBM.

That error code comes up when a key is used a different machine, each machine has its own licensce.

 

the T450 should have a key in the UEFI which is unique to that machine as it came with Windows 8. Check to see if there is a sticker under the battery with a key in case it was Windows 7 preinstalled.

Hi MountDoom and welcome to the Community,

 

It seems MS is having some activation problems.  Your problem might have something to do with this:

Try running the troubleshooter described in the article and see if anything changes.

 

Regards,

Dave

Re: T450s Windows 10 Pro Activation Failed

After I replied to the OP I notice a few more issues with Windows 10 version 18277

 

Windows 10 pro which is what Lenovo usually gives to X and T series users, was being downgraded to home edition etc

 

I reported it to my contacts at MSFT to check to see if a server is malfunctioning

Hi vegan-fanatic,

 

MS opened a thread on that also.

Hi topmahof,

 

Thanks very much for the help. I was randomly able to fix the problem yesterday. Basically, I retrieved the licence key by using a command in the Windows PowerShell. The licence key didn't work!!! I tried it multiple times, until it worked yesterday! And then I saw your reply which made sense. I think Windows was just being Windows!

Hi MountDoom,

 

I'm glad you figured it out, I think some of us are just going to have to wait for MS to straighten things out.

Dave
