Microsoft has made each and every effort in order to make Windows 10 licensing convenient. That said, there are times where product activation might not work according to our plan. If you want to perform a new install or also transfer your Windows 10 license to a new computer. Then your product key is a necessary asset that you need to have. Depends on how you acquired Windows 10, you might not have a Windows 10 product key, in most of the cases you do, let’s see how you can find it.

How to Find Windows 10 Product Key

First, let’s start with a purchased Windows product key or license because it is officially known. Windows 10 is actually licensed as a digital download or a full packaged product that you guys can also purchase at a physical store too. Both Microsoft and are actually the only authorized online merchants from which you can purchase a digital copy of Windows 10 as well. However, any other retailer that sells you just a product key is likely, not genuine actually. So, make sure you purchase a license only from Amazon or Microsoft if you guys decide to go the digital download route as well.

Another important tip, if you guys buy a license from Amazon, then use this link. Some also have tried to save a few bucks through purchasing a license from the Amazon marketplace. Only to later find the license is an MSDN key and not valid too.

When you guys purchase your Windows 10 license from the Microsoft Store, a copy of the product key is saved in your Microsoft Account actually. Microsoft will also send you a copy of the product key in a confirmation email as well. If you do not see the confirmation email, then check your junk mail folder. If you still do not find it, then log into the Microsoft Store > Downloads > Product Keys > Subscription page as well. Then press the Digital Content tab in order to see your previous purchases along with your product key.

Amazon customers can visit the Your Games and also Software Library section of the website to find your product key.

Windows 10 Pro Pack key

If you purchased a license through windows 10 easy upgrades in windows 10 home. Then you do not receive a windows 10 product key as well.

A windows 10 license will then assigne to your online Microsoft account.  All we need to do is sign in to your Microsoft account in order to activate the windows 10 license on a new machine as well. If you want to do this follow these steps.

  • Tap on the start menu, Tap on Settings / Cog Icon
  • Then click Update & security
  • Tap on Activation in the sidebar
  • Tap Troubleshooter
  • Now sign in with your Microsoft Account
  • When the wizard is completed, then Windows will indicate a digital license for Windows 10 has found
  • Tap on Activate Windows then follows the prompts.

Retail Full Packaged Product

Windows 10 is also available as a retail full packaged product that you can also buy at a store. Inside the Windows 10 product box, you guys will find your product key on a small business card at the back too. Users should make sure they save the product key in a safe place or have a backup copy of that too. I also recommend you to use our trick to take a picture of the key and then save it online for safekeeping.

OEM System Builder License

Older machines basically come with what is called an OEM Product key. This license key can be re-used if you want to re-install windows 10 as well.

  • An OEM product key is actually written on a label that is attached to the base of your machine. The OEM label will then look like the one below.

  • If you guys have a laptop then you might need to open up the cover to locate this label
  • I also recommend you to try Method 2 just to check the product code that has applied to your windows 10 is the same as the one on the sticker as well.

Using the Command Prompt

In order to do this, type “cmd” in the Windows search bar. Command Prompt will then appear in the search results. Right-tap it and choose “Run As Administrator” from the window that appears. If prompted, now enter your Windows account password.

When open, copy and then paste the following command and then tap the Enter key:

wmic path softwarelicensingservice get OA3xOriginalProductKey

The 25-digit product key will then appear to your screen.

Note: This method basically displays the Windows product key saved in your computer’s BIOS or UEFI firmware. In other words, it basically shows the original Windows key that your computer came with. If you have installed Windows along with a different key because then (or acquired a digital license). It will be different from the current key in use on your PC. If you want the current key in use on your PC, then NirSoft’s ProduKey is a good graphical tool to find it.

This way is instant, however, this is not likely a code that you’ll remember very easily. If you’d like a faster way to access your product key in the future, then you can use the Windows Registry method rather.

Using a Windows Registry Method

First, you have to open Notepad by right-clicking anywhere on the desktop. Hovering over “New,” and then choose“Text Document” from the menu.

Then copy and paste this code into your Notepad:

Set WshShell = CreateObject("WScript.Shell")
MsgBox ConvertToKey(WshShell.RegRead("HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\DigitalProductId"))

Function ConvertToKey(Key)
Const KeyOffset = 52
i = 28
Cur = 0
x = 14
Cur = Cur * 256
Cur = Key(x + KeyOffset) + Cur
Key(x + KeyOffset) = (Cur \ 24) And 255
Cur = Cur Mod 24
x = x -1
Loop While x >= 0
i = i -1
KeyOutput = Mid(Chars, Cur + 1, 1) & KeyOutput
If (((29 - i) Mod 6) = 0) And (i <> -1) Then
i = i -1
KeyOutput = "-" & KeyOutput
End If
Loop While i >= 0
ConvertToKey = KeyOutput
End Function

Next, tap on the “File” tab and choose “Save As.”

In File Explorer, just set the “Save As Type” dropdown to “All Files” and give your file a name. You can also use any name, however, it has to be a .vbs file. You can also name it something like: productkey.vbs

When you’ve entered a file name, then save the file. You can now see your Windows 10 product key at any time through opening the new file as well.

Volume License Product Key Activation

If you’re using Windows 10 in a business environment, editions like Windows 10 Pro, Enterprise, and Education do not use normal product keys. Rather, Domain Administrators set up special KMS (Key Management Service) servers that manage activation across the business network. This eliminates the need for computers in order to connect to Microsoft for activation.  System Administrators responsible for deploying Windows 10 in an organization can also find the product key from the Volume License Service Center portal as well.  Tap the Licenses tab, then press the Key tab for your Windows product too.

Imagine or Microsoft Campus Agreement

If you guys received your Windows 10 license via a Microsoft Campus Agreement or service like Imagine, formerly called Dreamspark. Then the product key should be available from the download page after purchase actually. A purchase confirmation email should also consist of a copy of your product key. Some Universities might also use volume licensing too. If your University utilizes KMS to handle product activation, then you will not receive a key actually. Rather, when you join the campus network or VPN in, KMS will activate your system automatically as well. This also means, that when you graduate or end enrolment, you will lose access to the license too.

Microsoft Software Developer Network

Subscribers to MSDN can also find their product keys by logging into their subscription. Select the product you would like to see press the product key button.

Damaged Product Key

Microsoft does not really provide much sympathy for customers who lose their product key. In some of the cases, you might be able to recover your product key via a key finder utility. Otherwise, if you lose it, then your only option is to purchase a new one. That is why you should always make a backup copy and also do not throw away the box too.

Users who took advantage of the free upgrade offer do not have a unique Windows 10 key actually. This is because of the way Windows 10 basically handles activation called Digital License. Folks who need to transfer their Windows 10 free upgrade to another computer are actually entitled to a one-time transfer right.

Help From Microsoft on Windows 10 Activation

Most of the time, after transferring a license or reinstalling Windows 10. You might have trouble reactivating the software actually. Windows 10 includes a handy chat option that you can use to contact a Microsoft support agent. They can help you with getting the software reactivated. If you guys prefer speaking to a live person, then you can also use phone activation.

  • Tap on Windows key + R
  • Then typeslui.exe 4 then click Enter
  • Choose your country from the list menu
  • Select the option phone activation, the wait for an agent in order to assist you.
