windows 10

Hi Geoffrey,

Installation of Windows 10 must be started while running a qualifying Windows OS (Windows 8.1/7 SP1).

How did you install Windows 10, by using a Windows update or ISO file?

If you have selected wrong edition of Windows or if you clean install Windows 10, it may ask for the Product Key.

What is the error message you receive, when you try to activate?

Why can't I activate Windows 10?

DreamSpark Windows Embedded 8.1 Industry Pro upgrade to Windows 10

@aaronfranke one thing considerably pushing me to find out why i am unable to reinstall clean fresh windows 10 pro on the same laptop before in which was installed activated windows 10 pro via the process of first windows preview 10130 and then to build
10240 and still activated but after that if you try to install windows 10 pro using an iso as a clean fresh install then during installation it ask for product keys and if you skip the activation wizard then simply you get error in the error saying some error
code that windows is not activated error 0xC004C003 ..so this myth doesn't apply to this insider program that if you first time upgrade to windows 10 and activated then Microsoft save Your laptop hardware specs and in future you will not need to enter product
key during reinstalling as a clean fresh install ..

 

anyone?

 

I updated my Surface Pro 2 from Windows 8.1 to Windows to 10 Friday and have Activation Error code is: 0xC004C003. I did not do a clean install but an upgrade using windows update which is recommended for initial upgrade I believe. I did a live chat and a remote session on the Surface with Microsoft yesterday and they could not resolve the issue. They could not find in the registry that I had installed using windows update. Once they saw that they moved me on to level 2 session scheduled for today.

During my install from windows update I got in loop of shutdown to restart and back into win 8.1 with a request to restart to install updates. This occurred several times. It finally installed after several iterations that ended up with the Surface Pro out of the docking station and plugged into the original power cord. May not be related but is odd

If I get any resolution today that may apply to a clean install I’ll post

 

I believe you need update you old OS to Windows 10 BEFORE doing the clean installation. The activation will then stay in place for the life of your computer.

 

I found that after my computer was upgraded to Win10, the MSDM table on the BIOS (which is where my Win8.1 key was located) no longer exists after the upgrade. I used Read Write Everything to look. The only other place it could be now is stored on your MS account in the cloud. So a clean install of Win10 on a previously upgraded machine would need to log into your MS account to activate. I think, heh.

 

Leave it for a couple of days, if it doesn't activate by then try activation by phone, very easy to use method.

Level two MS advised me to revert back to 8.1. Said they don't have much time or much history with fixing activation issues. I went to backup in settings, clicked the revert button and had dinner. When I got back I was in 8.1 was restored. Since I had an activation issue, there advise was to wait a couple of months for activation issues to be resolved and then try again. Or I could try to again now through windows update... I'm waiting for later.

 

BS. I fresh installed after upgrade from Windows 7 with no problems and, although I have an MS account, it was not associated with my Windows 7 account. You should quit spreading these ill thought out speculations.
