The vast majority of desktops operating around the world are based on Windows 10 . This is largely due to the efforts that these years have made from Microsoft to bring us updates and improvements almost constantly.
In addition, the market penetration figures of the operating system we are talking about are constantly growing, something that has no signs of changing in the near future. Something that we must bear in mind is that contrary to what happens with many Linux distributions, Windows 10 is not free. Thus, depending on the version of the operating system for which we choose, their prices start today from 145 euros.

For everything to be legal and we can enjoy all the functions available in this software, we must have our own product key. This is actually the one that uniquely identifies our Windows 10, as it happens with many other software solutions. Let’s say that it is the equivalent of the DNI of each one of us, but on the PC. That is why in most cases we are interested in making a backup copy of the Windows key.
This is something that we can carry out in different ways, however it may be, in most cases it is the most recommended. Otherwise we could run into a serious problem unexpectedly. This is precisely what we want to talk about along these lines, about the risks we run by not making said backup .

Lose Windows 10 key forever
In the event of some kind of catastrophe on our Windows 10 computer, if we cannot reboot the operating system again in any way, we will lose the key forever. If we do not have a backup copy of it, whether it is an OEM or retail Windows, we will lose that license, with the problems and annoyances that this could cause us.
Unable to update PC hardware
On the other hand, if we do not have a copy of this element that we are talking about, especially if it is retail, when we change an important component, Windows will ask us for it. Of course, we will not be able to provide it, so the only way out may be to reinstall and use the old component and make a backup of the key we are talking about.
Having to pay for a new key due to a virus attack
If we suddenly suffer, for example, an attack by a virus, ransomware or any other type of malware that blocks access to the system, we will not be able to recover your password. Therefore, if we do not have it conveniently stored in a safe place, we lose it, and therefore we will not be able to use it if we decide to format the system in its entirety.
We will not be able to change from computer to a new one
If we have a Windows 10 with a retail license , that backup that we are talking about will always be useful to us. The reason for this is that it is our property and is not associated with any hardware. Therefore, if we have it saved, when changing PC for whatever reason, we can enter it in the new one. Otherwise, we would have more problems , to the point of losing it if we cannot access the old PC.
