I recently purchased an online product key for Windows 10.   The key successfully activated, so does that automatically guarantee genuine?  Otherwise is there another way to confirm the legitimacy of the key?  Is there a method to do an audit test?

I guess there is no other way than activate it at the moment, so I guess at the moment that would mean that key is genuine.
Since windows 10 just showed up I guess there's no need to worry.

Hi Lance McGrew,

As per Microsoft:

If you're seeing notifications that the copy of Windows that is installed on your PC might not be genuine, or that you might be a victim of counterfeit software, it's likely that your copy of Windows was not properly activated or is otherwise not genuine. To fix this, click the notification and follow the steps to either repair Windows or—if you have inadvertently obtained counterfeit software—buy genuine Windows.

Until you correct the issue, you'll receive periodic reminders that Windows is not genuine. In addition, to more clearly display these messages, your desktop might turn black. You can reset it, but every 60 minutes, it will return to black until the issue is resolved.

Regardless of genuine status, Windows will still be able to get critical security updates. However, access to optional updates or benefits available exclusively to genuine Windows customers, such as Microsoft Security Essentials, might be restricted.

@Lance McGrew - Did you purchase your key from Microsoft?  I don't think there are many retail channels for Windows 10 one day after.

Yesterday I received an email from titled The public release of Windows 10 is here with a link to download the ISO.   I installed the ISO and found an online 3rd party seller with Windows 10 product keys.  I purchased a key and activation was successful.   MS website indicates during the check for updates, a genuine product key is tested.  So far, Windows 10 has installed two OS updates and one security update.   Leads me to believe the key is legit.
JohnBusiness Consultant (Owner)Commented:
I got the Gabe emails and I am on the Fast Track, so that is all legitimate. If you got a good paid key from Microsoft, you are good to go. All is well.
Lance McGrewRETIREDAuthor Commented:
As stated above, the key was purchased online from 3rd party not MS.   So this we know, the ISO was downloaded from Microsoft making it genuine.   I would think if the key was somehow counterfeit, it would not activate and as a post test, the updates would not install.   Right?
JohnBusiness Consultant (Owner)Commented:
The key and the download are different things. I am sure the download is good. However that will not make the key genuine at all.

You need to somehow check out the third party to make sure your purchase was genuine. Windows 10 has a retail price of about $120. If you paid significantly less (or even if not), you need to check out whether the key is legitimate.

Go to and search for "Is my Windows genuine". That should take you to a Microsoft site where you can test your key.
Lance McGrewRETIREDAuthor Commented:
Can you provide a link?   I searched all over MS for such a validation test and find nothing.
JohnBusiness Consultant (Owner)Commented:
Start here:

And also contact the vendor you purchased the key from.
Lance McGrewRETIREDAuthor Commented:
Already researched the link you provided.   Seriously, you think asking the vendor if they are legitimate would yield anything but "of course we are" answer?   :)
Lance McGrewRETIREDAuthor Commented:
Seems like there should be a simple online form field to plug in your product key and have it tested.
JohnBusiness Consultant (Owner)Commented:
The plug in links precede Windows 10 and the majority of Windows 10 systems are upgrades, not purchased.
JohnBusiness Consultant (Owner)Commented:
Try this page.

Where did you purchase the key?  Post the link.
Lance McGrewRETIREDAuthor Commented:
John, the link you provided is for activation errors.   I did not experience any activation error(s).
JohnBusiness Consultant (Owner)Commented:
Where did you purchase. I do not yet see a database for Windows 10 keys. It was only out yesterday.

Link for purchase please.

Here is a more elaborate discussion on Windows 10 validation .  There are links farther down to click on.

I do not think you are going to find a historical check for Windows validation because it is too new.
