Product keys are a standard feature for software and OS downloads. Microsoft has been using product keys for the longest time. Think of this as a digital license to use the operating system. Windows 10 is no different either. Windows 10 has two basic editions – Windows 10 Home and Windows 10 Pro. The Home edition is the foremost edition, which has decent features and is ideal for regular users, while the Pro or professional edition has better security features and is designed for small businesses and professionals. To use the pro edition, you need the Windows 10 Professional key. Here is a quick guide on buying and using a key, with other aspects worth knowing.

Installing Windows 10

It is possible to install Windows 10 Pro without a key. However, your desktop will have a watermark that says “Activate Windows”, and to be fair, it can be pretty annoying. Also, you cannot access all the relevant and important features, which is a bummer, give that people get the Pro Edition for the features. To activate Windows, you need the 25-digit product key. Each key is unique and can be used for one system or computer only. So, if you have four desktops in the house, you need four keys.

Buying keys for Windows 10 Pro

Microsoft sells Windows 10 pro keys on their website, but if you want to save some money, you can check for third-party vendors that have OS keys at a discount. The discount is because of the nature of deal that these vendors have with resellers. These vendors buy bulk retail keys from resellers and sell at a lower price to customers. To buy the key, simply pay the asked price, and your Windows 10 key will be sent to you on email.  You can go to the “Update & Security” section of your computer and find the option called Activate Windows. You can enter the key and your Windows 10 Pro will be activated instantly. Note that you need active internet to complete the process. This is a onetime thing, and all other Windows 10 updates will be offered by Microsoft for free.

In conclusion

Make sure that you are using the right key for activating Windows 10, and do not attempt to use the same key for other systems. Buy from the right vendor, and you can expect to get considerable support for all relevant aspects, in case the Windows 10 key doesn’t work as intended, or when you have other queries.
