Windows is authorized software and often requests you to activate your windows if it has yet to be activated. Therefore, you may wonder if there are any significant flaws to not starting your windows operating system.

What reasons behind not Activating Windows 10?

Windows is known as the most popular operating system all over the world, and then it is often the victim of piracy. As a result, Microsoft came up with a solution. And the answer is in the form of an activation key. Once you install Windows on your computer, you must provide an activation key.

What is the activation key? An activation key is the product key, which contains 25 number series that can help you activate windows. And when you enter the key, your Windows version will be unlocked on your device.

But later, Microsoft realized that many people were using their software without activating the windows. So, they are better off letting people use their software like this. And through this, they are still making money. In this way, Microsoft is more generous about its software usage.

Remember that an unactivated windows operating system always has a permanent watermark on the bottom right of your display asking you to activate windows. And it will remind you to start your windows through a pop-up menu which is more annoying. On installing Windows, your computer will ask you to activate it within 30 days daily.

Reasons if you don’t Activate Windows 10 After 30 Days?

After installing the windows, they will give you a 30-day free trial of the windows you are using. During this free trial of 30 days, windows will allow you to use all the features without any limitations. The entire windows will be available for you. And when this 30 days trial passes, all the availability or customizations will go away. Now is when you will be introduced to a generous version of windows. A watermark will also appear on the bottom right of your screen, telling you to activate your windows.

There are no such significant drawbacks to not activating windows, but if you do not, you will feel uncomfortable using it because of your lack of control over how your computer looks. But you can use your windows even after the 30 days trial.

Is Windows 10 Activation Permanent?

If your Windows is not installed by default and you have installed it through a copy version to purchase it from the store, you can install and download it as often. The Activation is compulsory, and on the other hand, the copy version is yours.

Before installing Windows 10, consider that your current software is updated. To update the existing software of your system, click on settings, then go to Update and Security and then click on Activation.

In case you don’t know what version of the software is running on your computer, then follow the following steps:

  • Go to the Start button and then enter Command Prompt
  • Type: slmgr/xpr and press Enter. This will let you know what software you are currently using.
  • After that, type slmgr/dli and press Enter key. This will let you know if your window is activated or not. 
  • In the end, right-click start and then press run. You have to type: winver ok, which will let you know what you are running and whether it is permanently activated.
