Microsoft has made a few noteworthy changes to how Windows 10 is activated, and most of them are for the better. They process has been streamlined, while also being made easier.
Depending on how you got your copy of the operating system, Windows 10 will either make use of digital entitlement or a 25-character product key. Digital entitlement is actually a new method of activation in Windows 10, where you are not required to enter a product key.
Now, while Windows 10 will usually notify you in case it is not activated, or there is a problem with activation, if for some reason, you want to check this manually, you can do so very easily.
This can be done either in the System panel, the Settings app, or even in the Command Prompt.
For the first option, simply open the Power Menu by hitting the Win + X keys on your keyboard, and then click or tap System. The following screen will be display, revealing the full details of your system, along with activation information at the bottom.
Another way to check is via the Settings app.
Open it from the Start Menu, go to Update & security, and click or tap on Activation on the left side.
If your copy of Windows 10 is not activated, these screens will make it very clear, and will allow you to activate your copy of the operating system. If it is activated, then you will see the below screen, that will display the details.
And finally, another quick way to check activation is by running a simple command in Command Prompt.
Open it, via either the Power Menu as noted above, or from the Start Menu, and then type the following command and press enter: slmgr /xpr.
Again, if your Windows 10 is activated, the above message will be displayed, otherwise the Command Prompt will notify you that the product key was not found.
