It will scan your local system and find the product keys for your Windows installation, Office, Adobe Acrobat, VMware Workstation, SQL Server and other softwares installed on your computer.

In addition, Password Recovery Bundle allows you to recover product key from a dead computer. Just hook up the hard drive of the dead computer to a working PC, and you can then find the Windows and Office product key directly in the registry files:

1. Open up Password Recovery Bundle. Click on Start Recovery and select “Product Key (Advanced)“.

2. In the pop-up window, click the browse button to locate the SOFTWARE registry stored in the hard drive of the dead computer. Typically, the default path is /Windows/System32/Config.

Find Product Key with Bootable CD

Is there an easy method to find product key directly from a non-booting computer? Password Recovery Bundle also allows you to create a bootable keyfinder CD, so you can easily extract lost product keys from your crashed or unbootable machine.

1. After starting Password Recovery Bundle, click on Windows Password and select “Create Password Reset Bootable Disk” from the menu that appears.


2. Choose a CD or a USB thumb drive and click on Start Burn to create a keyfinder bootable media.


3. Insert the bootable media into your crashed computer, and let it boot from CD/USB. To do this, you may need to change the boot sequence in the BIOS.
