PK Finder

Windows doesn't exactly make it clear how you can retrieve your product key, which you may need at some point. Fortunately, there are easier way of getting this information. A good example is PK Finder, which can provide you with the information instantly. It doesn't do much, except displaying your operating system's product key, which is all you can really ask for.

PK Finder is offered as a freeware application. It works on all popular Windows platforms, including Windows 10, and it supports both 32 and 64-bit versions. It can be installed in just a few seconds and it doesn't have any special hardware or software requirements.

You only need to launch the application and you will be all done. That is literally all you have to do. PK Finder will immediately display your operating system's product key on its compact user interface. At this point, you can just copy the key somewhere safe. An option is available right next to the key, which will copy the information to the clipboard.

A few basic options can be found in the general settings menu, for setting the application to check for updates automatically or to display a message when you copy the product key to the clipboard. You can also find options for changing the color and style of the user interface. Beyond that, you don't have anything else to do, except for being glad that you have managed to recover your system's product key.

If you can't find your operating system's product key, PK Finder will save you from this predicament at a moment's notice.
