Got my HP Stream 11 - 6 years ago with Win 8 preinstalled product key included. Since then upgrade to 8.1 and a year ago probably Windows 10. Needless to say performance was poor due to 2Gig of RAM and 30gig hard drive. But back then upgrade was mandatory...Decided to roll back to Win 8.1 however I get Error code: 0xC004C003 Activation key has been blocked..
and was fully activated before I updated to windows 8.1. And as far as I know, system which comes with preloaded window 8 has its product key injected to the motherboard and 8.1 is a free update for window 8 users.
We can't activate Windows on this device because you don't have a valid digital license or product key. If you do think you have a valid license or product key, select Troubleshoot below. Error code: 0xc004c003
All to no avail. Lastly, I tried the phone activation again but managed to get connected with a human agent. After obtaining the necessary information for him he told me that the product key was blocked by Microsoft and gone "back to the manufacturer" (Dell) and that there is nothing he or Microsoft could do.
First of all, how the fork can Microsoft block a product key they (presumably) sold to manufacturers like Dell (which then burns it into the BIOS of a single system)? And worse, why is Microsoft even pointing to the manufacturer when it's Microsoft which blocked the key and which could easily remove the block?
True (and I have amended my original post to reflect that it's IoT) but that doesn't change anything regarding the original problem, which is that Microsoft for some reason has blocked a completely genuine product key while pointing fingers to Dell for resolution, leaving me hanging in the middle.
This article describes an error code 0xC004C003. There are cases which have been discussed related to product activation and licensing related issues due to the hardware changes. If more no of activation are being done using the same product key, it may cause windows product activation issues.
In other words, the activation keys are blocked, try to take the assistance of a technician here. So that we can track the product keys on Microsoft Product code activation pages to verify the validity. 1e1e36bf2d
