Your Windows 11 product key

Future-proof and trend-setting

Windows 11 Pro is convincing all along the line – and especially in direct comparison with its predecessor. The development team was able to iron out various weak points and continue to rely on old strengths. These efforts become clear with a look at the extended features with which you as a user clearly stand out from Windows 10:

The first-class design combines efficiency with a pleasant appearance. Conveniently, the taskbar including the start menu will be centered in the future.
Microsoft Teams will (as in Office 2021) become an important partner who supports you in questions of communication as well as in everyday tasks.
Does your PC need to be equipped for the latest computer games? With the download of Windows 11 Pro, your system evolves into a console. Xbox says hello.
The annoying choice between 32-bit and 64-bit is now completely eliminated. The support for the outdated architecture has finally been officially discontinued.
An Android app that could previously only be used on modern smartphones is gaining scope with the Windows 11 release. Simply go to the Microsoft Store and download it.
Simultaneous work reaches its peak. Snap Assist creates groups that are exactly what you want, bringing each individual element to the fore.
Modern algorithms enable the use of numerous widgets that complement the core offering of Windows 11 Pro. Freedom of design remains essential.
A large number of other functions rounds off the scope.
There are also additional attributes that increase the contrast to Windows 11 Home:

Your advantages with Windows 11 Pro

Attention companies! Buying Windows 11 Pro unlocks everything the Microsoft experts have to offer. The security of your own data is particularly important. You can create sub-accounts and manage them separately, which allows you to define specific areas of application. Individual identities are therefore protected against targeted attacks. In combination with the appropriate group policy, your antivirus can breathe a sigh of relief. Everything relevant is on secure Windows servers.

Meanwhile, the deployment of Windows 11 Pro is extremely dynamic. Complete the download, follow the wizard and you’re done. Even a remote-controlled installation is conceivable, which the control center takes over in a relaxed manner. In general, mobile devices are increasingly coming into focus. The cloud-based administration is state-of-the-art. Not to forget the popular device encryption via BitLocker. Again and again recognized specialists emphasize that the precision of the underlying process is unmatched. Even if the device is lost, third parties have no access without the necessary identification.

In this respect, the small surcharge is more than justified in our opinion. Buying Windows 11 Pro is worth it.
