PK Finder

In the eventuality that you are planning to reinstall Windows, but you are unable to find the product key, then one of the first places to search for it is in the registries. If you are unable to access the files in the registry, then do not fret as there are many apps out there that can lend you a hand.
PK Finder is a lightweight piece of software designed to help you recover the serial product ID for your Windows with just one click.

Quick setup and sleek interface

The installation is a swift and straightforward process that does not take too much time and does not require any special attention from your part. Even though it is rather small, the program comes with an appealing and modern interface that is unlikely to give you any troubles.
It is worth mentioning that the application automatically detects the Windows version you are currently running on your computer. Moreover, the information is displayed clearly in the interface and the data can come in handy when you are searching for drivers for your hardware, for instance.

Retrieves the product ID automatically

As previously mentioned, the utility displays the version of Windows you are running along with the serial key in the dedicated checkbox. At the same time, the application includes a copy to clipboard function so that you can save the serial key in any desired third-party tool or the next editor installed on your computer.
If you are not using the clipboard, then you can export the serial key to a plain text file and save it to a USB Flash stick so that you can have it readily available for when you are reinstalling the operating system.

A reliable tool for retrieving Windows keys

In case you want to reinstall your operating system but cannot find or extract the serial key through the traditional methods, then perhaps PK Finder could come in handy.
