Is Windows 10 illegal without activation? – Here’s the truth!


Windows 10 is a very common operating system, without which multiple computers and laptops cannot function. 

The latest models of computers come with Windows 10 pre-installed. This means that you don’t have to buy it separately. But what if you have an older model or any computer that does not already have Windows 10? Well, you will have to buy it.

Most of us don’t do that, though. We continue using the trial version for as long as possible. But is that fair? Is it okay not to activate it? We are going to clear your doubts in this article.

Is Windows 10 illegal without activation?

No, Microsoft allows you to use the operating system for around a month without activation. They have a 30-day trial period during which you don’t have to activate it. 

So, using it without activation is not illegal. But, if you activate it using fraudulent means you will invite trouble. It is sadly a common practice to use an illegal product key to activate the system. If Microsoft finds out, you will be penalized.
