In a previous article,

To identify the product key of the
currently installed Windows operating system, download ProductKey, a free utility
that does not require any installation, you can simply
run it and it will automatically list the
product key of Microsoft Windows, Microsoft Office ,
and other programs.
There are two versions of this
utility, a 64-bit and a 32-bit . So all what you have to
do first is to identify if you have a 32-bit operating
system, or a 64-bit operating system.
To identify your system type, right click on
Computer and click
Properties

Inside the System Properties page, the system type will be
listed. As shown below, I have a 64-bit operating
system.

-
Now download the appropriate
ProductKey build that suites your PC (
32-bit or 64-bit )
Download ProduKey for x86 ( 32bit )
Download ProduKey for x64
-
Extract the downloaded file, and run
ProductKey.exe application

-
The installed Windows
operating system, Microsoft Office and
many other installed applications will
be listed and their corresponding
product key as well.

Write down the information you need or
even save the information in a text
file. Right click the software name, and
then click Save Selected Items

Give the text file a name, choose a
directory and save it.

The below snapshot shows how the output
file looks like. Of course I removed my
own product key :)

Now the next time you want to format
your computer, you don't have to worry about what is
your Windows 8 product key.
