I logged into an MS account once I installed Windows 10 thinking that would help. I made sure that my Windows 10 upgrade was activated first.

No matter what I did the clean install wouldnt activate and would give an Error Code 0xC004C003. After I upgraded and activated I did a clean install from a USB created with Media Creation Tool from MS. Upgrading I was able to activate with no problems every single time. I had several systems that I upgraded Windows via Windows update etc. I have tried several times to activate my Windows 10. To everyone doing a clean Windows 10 install and been getting an Error Code 0xC004C003 for several days with out activation. Using an ISO from a torrent or from the Media Creation Tool is not the issue here. I think that Windows 10 is a great product but I am tired of spending countless hours with Microsoft trying to activate validly purchased products due to their draconian licensing processes. I've started spending more of my time in OS X as a result of this upgrade process. I have too much time invested in doing multiple upgrades, backups, restores, and reinstalls to keep doing this. I believe that MS product management needs to change its policy to allow those of us with legitimate copies of Windows that can prove it to be issued a new product key to activate our valid copies of Windows 10. It may be the change to the 64-bit version even though MS clearly states that changing versions will have no impact on the activation. My log files from the upgrade indicate successful activation and my HW information has not changed so I can only assume that there is something else blocking my clean install. I assume that this information is the HW fingerprint that they will use to periodically use to activate and authorize our machines.

MS technical support keeps giving me lame excuse that the servers are still overloaded yet I've done a few other upgrades on other machines that activate immediately.ĭuring the upgrade process, some basic information on the hardware configuration is sent to Microsoft about a dozen times. The install ran flawlessly, but 7 days later my installation still has not activated.

I did a clean install on the activated system with an ISO version that I created from the Media Creation Tool. Also I wanted to move to the 64-bit version. Later that evening I decided to do a clean install because of all of the extra cruft that Dell installs and that I no longer need after migrating from Vista to Windows 7 to Windows 10. I too followed the directions explicitly and upgraded from Windows 7 Professional to Windows 10 Professional 32-bit.
