We're non really sure why Microsoft went to bang-up lengths to make information technology difficult to see the product keys for their software, especially since they are stored right in there in the registry and can be read past software, if not by humans. We tin can only assume that they don't desire everyone to re-use a cardinal from an old computer.

The key you need will exist in ane of three places:

Stored in software on your PC: When you lot (or your PC manufacturer) installs Windows, Windows stores its production fundamental in the registry. You lot can extract this product cardinal, and–often–enter it when reinstalling Windows on your PC. Crucially, you'll demand to grab information technology from your operating system earlier yous brainstorm reinstalling Windows or it could be deleted if y'all format your hard drive.
Printed on a sticker: Some PCs apply a technology called "Organization Locked Pre-installation," or SLP. If your PC uses this, the product key on your PC–the one stored in the registry, and the one cardinal-viewer applications display–will be different from the actual key your PC needs. The actual key is on a document of authenticity (COA) sticker on your PC or its power supply. The one in the registry and cardinal-viewer application is a ruby-red herring. This organisation was common for Windows vii PCs.
Embedded in your PC's UEFI firmware: Many newer PCs that come with Windows 8 or 10 apply a new method. The key for the version of Windows the PC comes with is stored in the computer's UEFI firmware or BIOS. You don't even need to know it–assuming you lot're installing the same edition of Windows the PC came with, information technology should automatically activate and piece of work without you needing to enter a key. It'll all happen automatically.

Exist sure to apply the aforementioned version and edition of Windows the computer came with. In other words, if it came with Windows seven Home Premium, you tin't install Windows 7 Professional person.

If the Key Is Stored in Your PC's Hardware

Permit's showtime with the simplest situation. On newer Windows 8 and 10 computers, the cardinal isn't stored in software where information technology can be wiped, or on a sticker where it could be smudged off or removed. No one tin glance at your computer'south sticker to steal its product key. Instead, the key is stored in the computer'due south UEFI firmware or BIOS by the manufacturer.

Yous don't have to do anything special if you take this. You should just be able to reinstall the same edition of Windows the PC came with and information technology should just piece of work without even asking you for a key. (Still, it may be best to find the product key using one of the below methods and write it downwards earlier reinstalling Windows–just in case.)

If yous want to find the UEFI-embedded key and write it downwardly, you can do so quite simply. But open the Outset carte du jour, type "powershell", and run the Powershell application that comes up.

And so, enter the following control and press Enter:

(Get-WmiObject -query 'select * from SoftwareLicensingService').OA3xOriginalProductKey

You should be rewarded with your embedded license fundamental. Write it down and store information technology in a safe place.

Read the Fundamental From the Certificate of Authenticity Sticker

If you have a Windows 7-era PC, there's a good chance the PC's primal is a single key the manufacturer uses for all their PCs. Cheers to "Organisation Locked Pre-installation," you're not allowed to use that key to install Windows. If you try, y'all'll become error messages most the primal being invalid.

To cheque, y'all'll demand to look for a certificate of authenticity sticker on your computer. The COA sticker verifies that the reckoner came with an accurate copy of Windows, and that sticker has a production key printed on it. You'll need that product key to reinstall Windows–and, if the manufacturer used Organisation Locked Pre-installation, that key is different from the one your PC came with in software.

Examine your figurer to find the key. On a laptop, it may be on the bottom of the laptop. If your laptop has a removable bombardment, it may be nether the battery. If there's some sort of compartment you lot can open up, it might be in in that location. It may even be stuck to the laptop's charger brick. If it'south a desktop, look on the side of the desktop's case. If it'southward non at that place, bank check the peak, back, bottom, and anywhere else information technology might exist.

If the key has rubbed off of the sticker, there'southward not much y'all can do. You lot can try contacting your computer's manufacturer and explaining what happened, but we can't guarantee they'll help. Microsoft would always be happy to sell you another key, though!

Employ NirSoft's ProduKey to Recover Product Keys (Even if Yous Tin't Boot the PC)

The easiest way to become access to your product key is with a third-party utility, and there'south nobody better at those than NirSoft. Their utilities are always crapware-gratis, and are always really useful. The only event with this particular utility is that some antivirus will notice it equally a false positive, considering some malware might try to steal your product central.

Note:the NirSoft keyfinder won't always work for OEM computers, depending on how they decided to activate the licenses. If your OEM installed your computer and used a single key for all their PCs, this won't work. It also doesn't work for Office 2013.

All y'all accept to do is download ProduKey, unzip information technology, and so run it to immediately see all of your product keys. It'south as unproblematic as that.

If y'all want to recover a key from a dead computer, you can hook up the difficult bulldoze to a working PC, and then run ProduKey and use File > Select Source to point to the external Windows directory. You can so grab the keys from that figurer easily.

You tin besides use a Linux live CD to pull the Windows directory off the other figurer and onto a thumb drive, or simply grab the registry files if you prefer. If yous demand help, we've got a guide to pulling data off a expressionless computer.

Discover the Windows Key Without Whatsoever Software (Advanced Users Only)

Assuming you can boot your calculator without any bug, you tin can easily create a simple VBscript that will read the value out of the registry and then translate it into the format that yous demand for reinstalling. We're not certain where this script came from, just reader raphoenix posted it on our forum a long time ago, and so we're sharing it hither for yous.

Re-create and paste the following into a Notepad window:

Ready WshShell = CreateObject("WScript.Shell") MsgBox ConvertToKey(WshShell.RegRead("HKLM\SOFTWARE\Microsoft\Windows NT\CurrentVersion\DigitalProductId"))  Function ConvertToKey(Cardinal) Const KeyOffset = 52 i = 28 Chars = "BCDFGHJKMPQRTVWXY2346789" Do Cur = 0 ten = 14 Do Cur = Cur * 256 Cur = Key(x + KeyOffset) + Cur Key(x + KeyOffset) = (Cur \ 24) And 255 Cur = Cur Modern 24 x = x -one Loop While ten >= 0 i = i -ane KeyOutput = Mid(Chars, Cur + 1, 1) & KeyOutput If (((29 - i) Mod half-dozen) = 0) And (i <> -1) Then i = i -1 KeyOutput = "-" & KeyOutput Terminate If Loop While i >= 0 ConvertToKey = KeyOutput End Office

Y'all'll need to employ File -> Save As, change the "Relieve as type" to "All Files" and then name it productkey.vbs or something similar ending with the vbs extension. We'd recommend saving to the desktop for easy access.

Once you've saved it, you lot can merely double-click and the popup window will bear witness you your product key.

Pro tip: If you use CTRL+C when the popup window is active, it volition re-create the contents of the window to the clipboard, and then you lot can paste it into Notepad or somewhere else.

The product central system is complicated to sympathize considering Microsoft doesn't really want typical Windows users to reinstall Windows on their PCs. Instead, they'd rather you employ your computer manufacturer's recovery media. But the recovery media is full of the bloatware you don't want on your PC–that's why so many geeks oftentimes opt to reinstall Windows on their new PCs.
