We introduce Windows 11 OS after 6 years from the last version. A functional, lightweight, and modern system that takes all the best features from Windows 10 to the next level. Furthermore, you may install and use the new Microsoft Office 2021 suite from day one since it will be 100% compatible and optimized for it.

The UI has been revamped, with rounded windows and a new arrangement for the Start menu, under the rules of the new Fluent Design language, that gives Windows 11 a modern look, optimized for multi-device experiences. Performances are higher thanks to the optimization provided by DirectStorage, while the new features for creators and developers will give you plenty of monetization opportunities.

Whether you’re a passionate gamer or a professional looking for the best performance for your job, Windows 11 provides you with all you need to get the most out of your machine. Thanks to the better integration with Xbox Game Pass and the new encryption features that leverage TPM hardware from your motherboard, Windows 11 will address all your needs. We always recommend protecting your devices by also installing a valid and effective Antivirus against cyber attacks.
