Product Key Recovery

Recover your Windows license key, Office keys, and saved WiFi passwords — the information you always wish you had before a reinstall.

What it does

Windows and Office store their activation keys in the system, but neither one makes it easy to read the key back. If you've ever been asked for your product key and had to hunt through a box or old email, you know the pain. TuneBit reads the keys directly from the places Windows keeps them and shows them to you on one page.

The three cards

Windows

Shows your edition (Home, Pro, Enterprise), build number, the 25-character product key, and the activation status (permanent, subscription-based, grace period, etc.). Click Copy to put the key on the clipboard.

For most modern PCs the key is embedded in the motherboard firmware as a digital license — this is a good thing; Windows can reactivate itself automatically after a reinstall. The key shown here is still useful for manual activations.

Office

Every installed copy of Microsoft Office — Office 2013, 2016, 2019, 2021, and retail installs of 365. For each one you'll see the version, the install type (retail key, volume license, subscription), and the last 5 digits of the key (Microsoft only records a partial for most licenses).

WiFi Passwords

A table of every WiFi network your PC has ever connected to, along with the security type and the stored password. Passwords are hidden by default — click Show Passwords to reveal them. Great for when you want to connect a new device to the home network and forgot the password.

How to use it

  1. Go to Info → Product Keys.
  2. Wait a few seconds for the scan. The Windows and Office cards populate first; WiFi takes a moment longer.
  3. Click Copy next to any key to put it on the clipboard.
  4. Click Show Passwords on the WiFi card to reveal the saved password column.
  5. Click Export at the bottom to save everything to a text file. Store it somewhere safe.
Before a clean install of Windows:
  1. Run Product Key Recovery and Export.
  2. Save the exported file to a USB stick, an external drive, or email it to yourself.
  3. After the reinstall, use the keys to reactivate if Windows doesn't pick up the digital license automatically.
Treat this file like cash. A product key is a transferable asset — anyone with a copy can use it. Don't email it to strangers, don't paste it into a forum for "help," and don't leave the exported file on a shared computer. If you suspect a key has leaked, contact Microsoft to block it.
WiFi passwords require administrator rights. If the column shows (access denied), re-launch TuneBit with Run as administrator. TuneBit normally elevates automatically.
