Windows deactivated after update

Question

So I have not updated for a couple months until yesterday (28/02/2025) I decided to finally update. It was a pretty lengthy update but I'm no expert so I didn't think much of it, probably just a major update or something.

It was when the update was complete and I was looking though my photos for a new background picture that it told me that my windows needs activating for personalization. I have bought my computer pre-built that came with windows home already activated, I had no issues for the entire year or so of use with windows activation.

I did a bit of research on the issue and have tried a few methods of which none has worked. I first tried re-entering the product key but it says that I "don't have a valid digital license or product key". I used ShowKeyPlus to check the product key edition and it says that it's for a "win 10 rtm core:nonslip", I'm not sure if that's normal because from another case I found of a similar issue also says that when they used ShowKeyPlus on windows 11

I have also tried using the code "slmgr /rilc" in cmd run under admin which is suppose to "reload license configuration files", whatever that means. I then restarted and it did nothing.

The only other possible cause may be the changing of RAM sticks? My computer had an issue in Nov/Dec 2024 with memory management but that was sorted out by the company's warranty, but they used the same model RAM from the same manufacturers. That and also I do remember updating at least once shortly after getting my computer back from them and it didn't have any issues with windows activation.

My next attempt will be getting my laptop an see if it also has windows 11 home, and if so, I'll try searching for it's product key and see if I can transfer the license over.

Answer 1

No worries, there's no PII in this screenshot.

You have OEM-COA-NSLP license.

This type of license is for builders who don't have capability like big OEM companies (Dell, HP, etc) to embed OEM license to motherboard. So it works like a retail license, but builders must put the sticker on the device that it came with. Look for this sticker on the device somewhere. Typically it is on the back of the PC tower. When you find it, you will see the license key on it.

Then go to Settings > System > Activation > Change product key, key in the license key and it should do the trick.

Here you go. Not sure if there's any sensitive information shown but if there is please let me know so I can hide it. Also, I have yet to use a different product key.
