No Product Key After Clean Install

Aug 12, 2015

My PC was running 8.1 French version converted to English version (Reseller screwed up).In practice a lot of the stuff was displayed sometimes in Eng sometimes in French. I have the 8.1 French CD.So instead of doing the upgrade which I thought would result in another mishmash of languages, I did a clean install of 10 Home Eng via USB key downloaded install media.Apart from a few video probs (BSOD) blinking cursor, all went well.I cannot use 8.1 product key to activate. Looks like I may have to buy new product key for W10.

How To Do Clean Install After Upgrade (No Product Key)

Sep 21, 2015

I recently upgraded to windows 10, and decided to do a clean install. So I made a image of my system (when it was windows 8.1), wiped my Hard drive (which still had the original windows 8 install,), and stuck a ios file on a usb stick. However during the install to my SSD (Which is different from my hardrive) the computer asked for a product code, something I do not have, and did not think I needed (my understanding was that windows 10 registered your hardware). If I skip it, it goes though the prossess of installing, but then restarts after finishing moving the files. I dont want to have to attempt to go though the effort of putting windows 8 back on the laptop, moving it over to the ssd, upgrading to windows 10, getting a product key that may or may not work, and trying it again.

Installation :: Will Update Provide A Product Key For Clean Install

Jul 28, 2015

Will windows 10 update provide a product key for clean install? If so how/where?

If not when performing a clean install, will skipping the product key prompt, then activating once desktop appears automatically activate and inject a product key?Lastly rather than extract the esd file, where to get a genuine Microsoft iso's on release date?

Won't Activate After Clean Install

Aug 9, 2015

I have been an Insider since the very first Insider build was released. I had installed each and every build first being on the Slow ring and the on the Fast. I had upgraded from a genuine Windows 8.1 Pro.

When the final RTM build TH1 Professional 10240 was released to Insiders ahead of schedule, I readily installed it and my machine was permanently activated at that time. The product key used was a generic one ending in 3V66T. Many of you may be knowing this.

Today, in fact just now, I formatted my system partition and installed a clean copy of Windows 10 Pro from USB which I had created using the Microsoft Creation Tool. When the setup asked me for a product key, I entered the same generic key as stated above. But now when I go to the Settings, it says the key doesn't work and hence, my machine cannot be activated. I signed-in using my Microsoft account before using the PC.

What the heck! I am an Insider. And didn't expect this to happen. What should I do next? Would the machine get activated itself after some time?

OS Will Not Activate After Upgrade / Clean Install

Jul 29, 2015

I upgraded from 8.1 (genuine Sony Vaio ) using the media creation upgrade option, it installed and activated to windows 10 pro.

I then used the same media creation tool to download the iso and used Rufus to put it onto a usb so that I could do a clean install.

I installed it and skipped the parts prompting for a product key, however once it loads up when I try to activate it states 0xC004C003 details section says the key has been blocked?

Have I missed something?

Updates :: Will Windows Activate Itself If Do Clean Install

Sep 14, 2015

If I understood this : clearly, then does it mean that Windows will activate itself from some Windows activation servers that are somehow written into my hardware even if I do a clean install deleting everything in my Windows partition?

Also, since the built-in "Create a Recovery Drive" will take forever or display an error when ''Backup system files to the recovery drive' is checked", I'm trying to create an Installation media. But I'm stuck with which ISO I should download. Now, there's Windows 10, Windows 10 Single Language, Windows 10 Home, Windows 10 Home N. I'm running Windows 10 Home at the moment. Which was upgraded from Windows 8.1(I think there was ''Single Language'' written after "8.1", not sure though). Which Version should I download. And if I install the wrong version by chance, will Windows still activate after I find out and install the right version? Please clarify these.... I'm really looking forward to do a clean-install to get rid of all the errors and bugs with drivers and just start over.

*DETAILS: Windows 10 Home Build 10240 [Upgraded via free upgrade, had an OEM version of Windows 8.1 when first bought]

Clean Install Lost Activation / How To Activate It

Aug 15, 2015

On both my main machines I was running Windows 8.1 and I then removed that and installed the Windows 10 insider program.I kept installing new builds until RTM came along. Once Windows 10 was released I unenrolled from the program and both machines were still activated.

I performed a clean Windows 10 install on one machine and now it is asking for Windows 10 to be activated and I don't have a key - am I basically screwed?

Installation :: Update Keeps Failing At 84% - Any Way To Do A Fresh Install And Activate

Aug 4, 2015

I have Windows 7 Pro on a Dell 5420 laptop. I've tried the upgrade multiple times and it always gets to 84% and then the screen goes black/blank. It sits there for upwards of a couple hours. After that it reboots and says Restoring previous version of Windows and I end up back at Windows 7.

I don't know if there's any logs somewhere I could check to try to figure out what the problem is.

Do I have any options for upgrading this laptop if the update from 7 to 10 won't work? From what I've read I need to get the in place update to work in order to get a valid Win 10 key so I might be screwed...?

Updates :: Unable To Activate After Clean Install Of 10586

Feb 10, 2016

Since the Win10 Upgrade fails on my HP DV6 notebook, I decided to do a clean install.

But now, it won't take the Win7 product key for activation!!

I called MS and they told me that a clean-install will NOT activate using Win7 product keys and that I have to purchase a product key.

I got this same story from two different MS reps.

I thought you COULD activate a clean-install using Win7 key using build 10586.

Unable To Activate Pro Version After Clean Install (error Code 0xC004C003)

Jul 29, 2015

I did a clean install of Windows 10 Pro x64 using the method that everyone knows about by now that was written up on various sites today i.e.:

Ran the Media Creation Tool and upgraded my copy of Window 8.1 Professional with Windows 10 Professional. Looked in Control Panel --> System and it said my copy of Windows was activated. Then I ran the Media Creation Tool again and downloaded the ISO. Burned ISO to DVD. Restarted computer, booted into Windows installer on DVD, customized the install by formatting drive, did a fresh install of Windows 10.

Now when I go into Control Panel --> System it says "Windows not activated". When I click on the Activate Windows icon and click the error details link I get the error code: 0xC004C003.

I should note that the Windows 8 OS came pre-installed on my laptop which I bought brand new. I don't think that matters?

Installation :: Keep Rebooting After Inserting Product Key

Sep 24, 2015

I have a new computer with windows 10, at the first boot the computer did some things to prepare itself for use, but then I was asked to give my credenitals to account, I used my windows account, but there was some error and I had to reboot. Since then this is what happens: when I boot up there is (probably, cause English is not my native language)

Then I choose my language and click next, after that it asks for a product key, after I confirm that (or skip) and use express settings it goes into "just a moment" than the computer reboot and I am at the begining again.

Installation :: Product Key Not Accepted (Duplication)

Dec 22, 2015

I have just restored a saved version of a VM Windows 10 upgraded from Windows 7. It had a digital entitlement but the restored machine required activation. I chose what I thought was the Product Key of the Win 7 machine prior to the upgrade but it was rejected. I now realise that I may have used the wrong key but it raises a question.

How can you tell what Product Key you have used to activate an installation of Win10 which shows as activated?

Retrieving Windows Product Key From BIOS?

Aug 26, 2015

How I can retrieve my windows product key from my BIOS? This for a 2 month old MSI Dominator GT72 PRO laptop which was purchased new with Windows 8.1 preloaded; no disc or product key label was provided. We recently did the free upgrade to Windows 10 and through a series of issues ended up letting the OS do a reset which did not work out.

Microsoft provided us a link to download Windows 10 for a clean install, which we did and is now on the laptop, however, it requires the original 8.1 product key to complete the installation. Microsoft tells me that the original product key should be retrievable from the BIOS since it was not provided with the laptop. What is the procedure to locate the key from the BIOS?

Installation :: Can't Upgrade To PRO / Can't Get Past Product Key Window

Jul 21, 2015

I am trying to upgrade GENUINE Windows 8.1 PRO x64 to Windows 10 Pro x64 from the ISO I made from the Microsoft RTM files. I am upgrading from within the 8.1 OS and choosing the option to keep "nothing" of my settings and personal files.

I have two problems.

The first is that the installation asks for a product key. On the other hand, when I upgraded my Windows 7 machine to 10 from within the OS it didn't ask for a product key. Why do I need to provide the product key to upgrade my 8.1 system, but not my 7 system?

Second problem is that I can not upgrade from 8.1 PRO to Win10 PRO. When I put in the general product key for the Win10 HOME edition the install proceeds, but it does not take the other (different) product key corresponding to the Win10 PRO version, even though it should. Why can't I go 8.1 PRO -> 10 PRO?

Updates :: How To Find Which Product Key Has Been Used For Installed Windows

Aug 28, 2015

Windows 10 x64

As I have multiple retail license keys, I am unsure which one is in use right now.

There are 3rd party key finders that may show the key in use, but I prefer to obtain the key using Windows own tools, if possible. For instance using a CMD.(Am uncertain about these 'key finders': can they be trusted?)

Windows Product Key On Label Differs To Retrieved Key?

Nov 30, 2015

apparently the key on the label is the OEM key the manufacturer is obliged to give with an OEM product.

the ' embedded' key found with magicaljellybean is the volume licensing key that the manufacturer uses to bulk activate multiple PC's not strictly a Windows 10 issue.

I did a product key search using jellybean on a Windows 7 PC I am about to upgrade to Windows 10. however the product key I obtained vqb3x .....etc is different from the product key on the sticker on the side of the PC.. .MMVJM....etc

why it is different ?
