When we buy a computer, in most cases usually it brings installed Windows operating system and hence do not need a CD or DVD installation or activation key. However, when for some reason we want to reinstall the operating system, we need the installed windows’ license key and product key.
Certainly a very embarrassing situation, because without this key we never reinstall the operating system. That’s why we will show below, some applications that will help us to recover the license key of your computer to save it and make reinstalling the system without any problem.
Recover Windows product key with these free applications
One of the most popular product key recovery applications in this regard that can recover keys Windows and other Microsoft tools such as Office, Exchange Server and SQL Server. It is an application that takes up very little space and also does not require installation, so we we can easily take on any USB flash drive to run on the computer you want.
Just run it will show a window with all system information, Windows ID and password, computer name, etc. Data can be exported to your desktop to save in different formats, TXT, HTML, XML, CSV or JSON.
RECALL key windows
It has a native version for both operating systems 32 and 64 bits and can be downloaded at no cost from the page Nirsoft to which we take from this same link .
Magical Jelly Bean KeyFinder
Free application that lets you recover the Windows key plus many other programs from Microsoft and other companies and developers. In addition to the free version, which allows you to retrieve keys installation of more than 300 applications, there is another payment that is compatible with more than 8,000, but both allow us to recover the Windows key.
When you start the application, you will quickly be able to show a panel where we can see the name of the product, your ID, installation source, etc. Save the data in a plain text file or CSV.
SterJo Key Finder
Again another free and portable application that can help us recover the keys of many programs, including the Windows operating system. The executable SterJo Key Finder occupies only 840 Kb, so we can take on any USB flash drive to run it on the computer you want.
Nothing launch the application, start to search and retrieve the keys to then save them in a text file and can subsequently use. The interface is very simple, as it consists of a list where we will show the installed programs and serial keys, if any. This information can be copied and saved if any problems.
It has similar functionality to the above applications, but if you are someone who have upgraded you to Windows 10 from an earlier version with the free promotion offered Microsoft during the first year of Windows 10, ShowKeyPlus show you the serial number original, ie before the update.
It is a free application and like the rest does not require installation. Once opened ShowKeyPlus, we will see a window that will show the product name of Windows, your ID, the installed key, the original, as well as its key OEM and editing. In this case, the serial number that interests us is the key installed, but we can not copy it from the window, for this we must save it to a file previously.
