Who has never been daunted by the price of a Microsoft Office 365 license and wondered if it’s piracy? While software piracy has long been the preserve of those in the know, the practice is becoming more common on the Internet. And that can help if you’re a student or want more than the LibreOffice/OpenOffice suite for your family’s computer. Often it is enough to type a request on Google, and apply an online tutorial to get the Grail: free access to Microsoft Office 365 or Windows. It sounds quite simple, but in reality, hacking poses serious risks to the user that could have been avoided. Indeed, services like Yeslicense offer reliable and safe solutions to find Microsoft Office or Windows cheap

Piracy: What’s Behind These Free Licenses?

In license piracy, the activation portion of the software is often illegal. This is done via hacking tools (hacking system), which make it possible to illegally activate a license. For Microsoft, a system called KMS (Key Management System) is used to activate the license. The KMS makes it possible to activate software on an individual’s computer thanks to generic keys legally stored on a server. These keys are generally renewed every 180 days. But the KMS activator can also be used for hacking purposes, by emulating a fake server. This activates the product for free, but free is not safe.

One of the first differences between a pirated version of an office suite and a cheap official license is found when the product is activated. For a hacked free version, you have to search tutorials and sometimes download third-party software that compromises your computer’s security. The process is not always easy, does not always work the first time and is not equally easy for everyone. Not to mention paying for each license at full price, you can use sites like Yeslicense that allow you to get a perpetual license at a low price. It allows you to download Microsoft Office or Windows in a completely legal, convenient and risk-free way.

Another disadvantage of the KMS activator is the length of the license. Indeed, an illegal activation key needs to be renewed very regularly. So you will have to go through the same activation process every time you need it. Where a cheap legal license remains active as long as a classic license. In the case of piracy, there is a lot at stake as you have to deactivate your antivirus every time to use the KMS activator.

A real risk for your hardware and your data

Finally, the main drawback of licenses activated through an illegal KMS activator is security. In order to provide illegal activation keys, security rules must be circumvented. That is, you need to disable your antivirus program in order to download and use the KMS. During this time, your computer will be very vulnerable and it only takes one infected file for a warning message to appear on the screen. An analysis of the first KMS activators listed on Google shows that most of these KMS activators have a high detection rate on VirusTotal and many other suspicious activity. In other words, if you rely on a KMS activator to get free Microsoft Office or free Windows, the risk of your computer being infected by one or more viruses, malware and all kinds of trojans increases significantly. Once entered into your system, the virus can greatly affect your computer. In some cases, it will be necessary to engage an IT professional, whose services will certainly be more expensive than the price of a license. To ultimately not be sure that you can recover your files and documents.


Aside from the ethical aspect, using a pirated software activation key takes more time (look for tutorials and regular reactivations of a key generated by a KMS activator), and you run a lot of risks. It is for these reasons that we advise you to go through Yeslicense to activate Microsoft Office or Windows on your computer.
