How can I find the product key that was used to activate Windows 8?

I have Windows 8 activated in my system. I don't have the product key of windows right now. Now I want to format my system again. Is there any way so that I can reuse the key? Is there any way I can get the key from an activated windows machine?

Edit: I am not able to find the product key because I have used a MAK as my product key. Now I want the same to use it after formatting my disk. I found a software Volume Activation Manager tool on the windows website. I am not sure how to use it. Please tell me how can I reuse my key?

This question has been asked before and already has an answer. If those answers do not fully address your question, please ask a new question.

    
@Karan: I have added some more details. Now my case is different form the link. –  Dibya Dec 16 '12 at 22:54
    
Is it a MAK or KMS key? Where did you get hold of the volume license key anyway? The proper thing to do would be to contact your organization and ask them to help you out, which they obviously should if all's legit. –  Karan Dec 16 '12 at 23:46
    
@DibyaRanjan where did you acquire said MAK in the first place? –  nhinkle Dec 17 '12 at 2:07

I found a site claiming to find lost product keys (I have no connection with them) Lost Product Keys

I am also wondering if the product key is stored somewhere in the registry, after all, how do these tools find it? My point it must be possible to do what you want, just a question of more time for research versus spending money to get the job done.

The Microsft legalities of what you do keep changing.
A) You could ring them!
B) I think it's OK providing you reformat the old machine.

+1 for giving all the related software. –  Dibya Dec 16 '12 at 22:55

If you want to know the product key of your Windows installation, I would suggest to install Belarc Advisor, a free online tool which gives you all the information about your PC including your license key.

Now, obviously, you'll ask me why you should install a complete system information tool just to know your product key instead of a standalone product key finder. I have tried other product key finder utilities like Magic Key Finder and some others (the ones in the first page of Google search results) but unfortunately none of them has told me the correct product key of my Window 8 installation (I was just checking, my product key is written on a paper and kept in my room).

This utility, however, told me the correct key of my system. So, just download it, run it and in the results, scroll down to software licenses and voila, your key is there.

Product Keys

Point to note: It didn't return the product keys for my Kaspersky (For Kaspersky, it only showed the Product ID and not the product key) and Office, so in case you want these, you have to look elsewhere.

Another point to note: If you have installed the Media Center Pack on your PC, the Windows 8 product key will be the key for the Media Center addon you added. And, no, this won't work when you're reinstalling Windows. Instead, look in the key which shows for Internet Explorer. This is the actual key you used during installation. I can confirm, in my case, it was the same key with which I installed.

Hope this helps!

Thanks @Pratyush but Belarc Advisor is not giving my product key. –  Dibya Dec 16 '12 at 13:42
    
What does it say? Are you using version 8.3? –  pratnala Dec 16 '12 at 13:46
    
I got result as: Microsoft - Windows 8 Enterprise (x64) 00178-50352-23007-AA843 (Key: BBBBB-BBBBB-BBBBB-BBBBB-BBFDP) –  Dibya Dec 16 '12 at 13:48
    
Umm does it say the same for Internet Explorer as well? –  pratnala Dec 16 '12 at 14:00
    
You could try this magicaljellybean.com But the reason I didn't recommend this is that in Windows 8 it showed me my key as BBBBB... basically what you're getting in Belarc. –  pratnala Dec 16 '12 at 14:02

use the tool Windows 8 Product Key Viewer. This seams to be the only tool to read the key in Windows 8.
