The problem
Most key finders show you the wrong key
On a modern PC the key in the registry is often Microsoft's public generic key. Show it as "your key" and you find out after the reinstall that it activates nothing.
A generic key shown as yours
Windows with a digital licence stores Microsoft's public default key. Many finders show it as if it were the key you paid for.
Demos that hide the key
Free versions that show four characters and a padlock, so the scan is free but the answer isn't.
Yearly fees to read a key
A subscription for something you need once per reinstall, renewing long after you have written the key down.
No explanation
A list of strings with no idea which is Windows, which is a volume key from work and which will activate after a reinstall.
Useless on a dead PC
The PC that won't start is exactly the one whose keys you need, and most tools can only read the running Windows.
Downloads you can't trust
Key finders are a favourite disguise for adware, on the very screen that shows your licences.
Vow Key Finder fixes all of it.
How it works
Open. Read. Keep.
The key that matters in big letters, what it means in one sentence, and a backup before you wipe the drive.
- 01
Open it: the scan is instant
It reads this PC by itself in well under a second. The Windows card shows the key to keep in big letters, with Copy, a QR code and one sentence on what it is.
Your Windows key explained, with Copy, plus every other key found - 02
See every other key
Office, Microsoft and program keys are listed with honest labels: verified, public key, last 5 only, licence file. Click a row for where it was found.
...with the other keys, and places to look somewhere else - 03
Back them up, or check one
Save a printable web page or a password-encrypted backup, or type any key into the checker to see which edition it is for.

Features
Every key, with the truth about each one
For reinstalls, new drives, old PCs that won't start and anyone who looks after more than one computer.
Your Windows key, explained
Installed key, the OEM key in the firmware and Windows' backup copy, checked against Windows' own licensing service.
Digital licences, not fake keys
When Windows needs no key, it says so, instead of presenting Microsoft's public generic key as yours.
Office 2000 to Microsoft 365
Full keys where Office stores them, the last 5 characters and product names for Click-to-Run, each explained.
Programs and licence files
SQL Server, Visual Studio, VMware, WinRAR, WinZip and more, plus a deep registry scan for keys no rule knows.
A Windows that won't start
Read the keys of another Windows drive or a Windows.old folder, user hives included, without changing a file.
Key checker
Type or paste any key: Windows' own checker names the edition, retail, OEM or volume, and spots typos, offline.
Saved Wi-Fi passwords
Saved networks are listed, with their passwords when you choose to restart the app as administrator.
Encrypted backups
Save a printable web page, text, CSV or a password-protected backup, and open your backup again after the reinstall.
Read-only and private
It never changes a key, a licence or the registry, nothing is uploaded, and privacy mode hides keys until clicked.
Light and dark theme
Paper-light or carbon-dark: switch with one click at the bottom of the side rail, and your choice is kept.
Light & dark theme
Easy on the eyes, day or night.
Key Finder comes with a crisp light theme and a calm dark theme. Switch with one click, or let it follow your Windows setting by itself. It remembers your choice.
- LightClear and bright for daytime and busy offices
- DarkGentle on tired eyes late at night
- Follow WindowsChanges by itself when your PC does

Who it's for

Before reinstalling Windows
Write down the Windows and Office keys, or learn that Windows reactivates by itself.
A PC that won't start
Put its drive in another PC and read the keys of that Windows, including each user's programs.
Moving to a new drive or PC
Save every key as an encrypted backup and open it on the new machine.
Finding an old Office key
Recover the full key of an older Office install, or see which Microsoft 365 product is installed.
Checking a key you were sold
See which edition a key is for and whether it is a public generic key before you rely on it.
IT and repair technicians
Network PC scans, many keys checked at once and command-line reports for the PCs you look after.

FAQ
Questions about Key Finder
Is Vow Key Finder free?
Yes. Your Windows key is always free: installed, firmware and backup keys, copy, QR code and saving it as text. Office and program keys are found and listed, with 3 revealed a day. Unlimited, a one-time $4.95 USD payment, reveals every key and adds full backup reports, network PCs and the command line.
Why does it say "No key needed" for my Windows?
Because Windows is activated with a digital licence tied to your PC or Microsoft account, and the key stored in the registry is Microsoft's public generic key. Reinstall the same edition and Windows activates by itself.
Can it find my Office product key?
For Office 2000 to 2013 installed from a disc or download, yes, the full key. Office 2016 and later store only the last 5 characters, and Microsoft 365 is licensed to your account; the app shows what is installed and says so honestly.
Can it read the keys of a PC that won't start?
Yes. Connect its drive to a working PC, or use a Windows.old folder, and choose Another Windows drive. Its registry files are copied and read privately, so the original drive is never changed.
Does it change anything on my PC?
No. It only reads: it never changes a key, a licence or the registry, and nothing is uploaded. It asks for administrator rights only if you want saved Wi-Fi passwords or a protected drive.
How is it different from ProduKey or Magical Jelly Bean?
It verifies the Windows key against Windows' licensing service, explains digital licences instead of showing a generic key as yours, labels every public default key, reads the firmware key and its edition, and includes a key checker and encrypted backups.
What is the key checker?
Type or paste any Windows or Office key and Windows' own checker, offline, says which edition it is for, whether it is retail, OEM or volume, its part number and whether it is a public generic key. It also spots typos.
Is it safe to install?
Yes. It is made and published by XTO Pty Ltd, an Australian company. The installer contains no ads, no toolbars and no bundled software, needs no administrator rights, and uninstalls cleanly from Windows Settings.
