One of the techniques Microsoft used to promote its new operating system in 2015 was to allow users to upgrade Windows 7 and 8.1 to the new Windows 10 for free . By doing so, the original Windows licenses became Windows 10 licenses, and thus the new operating system could be legally used without problems. This promotion was only valid for the first year, although it was officially extended a bit more until 2017. However, although in theory this promotion should no longer be in force, it is still possible to update our computers for free with a simple trick .
Currently there are several tricks to update Windows for free to the latest version. One of the best known is the assistance tool, which allows us to install the new version through a small “bug” while maintaining our original license. But there is another much simpler technique that does not need to take advantage of failures or errors, simply prepare the system and download a tool to make the jump from Windows 7 to Windows 10 completely free of charge. And, of course, 100% legal.

Prepare the system and update the license
The process to upgrade from Windows 7 to Windows 10 for free is not precisely characterized by being reliable, but has always been characterized by all kinds of problems. Therefore, before starting the process, it is advisable to take into account some small recommendations and carry out a series of basic tips:
- Install the latest version of all PC drivers to avoid canceling the process due to using old drivers.
- Disconnect all external devices via USB, such as memories, printers, hard drives, etc.
- Uninstall any antivirus that we have installed on the PC, since these are the most common cause of errors.
If everything is correct, we will simply download the media creation tool from this link, run it and follow the wizard to update the PC. During the process (which can take a long time), Windows 7 will connect to Microsoft’s servers and upgrade the license.

Once this is done, the license of our PC will have been updated to the new Windows 10. This license will be recorded in the UEFI of the system, and linked to our Microsoft Account, and will allow us to activate Windows even after formatting and installing the operating system from scratch .
Windows 7 is still installed on 20% of computers
Windows 7 has been one of the best versions of the operating system. However, since January of this year, it no longer has support . Any security flaw or vulnerability that is discovered for this system will irreparably jeopardize our security. The only way to be sure is to update the system to a more modern version of the operating system, either 8.1 or, the best option, Windows 10. Also, taking advantage of the trick that we have just explained, we can even make the leap to the new operating system completely free of charge , without going through the box.
Even XP continues to have a presence today with just under 1% market share, an operating system that, since 2014, has gone down in history. Of course, the upgrade promotion does not include upgrading from XP to 10.
