Microsoft is still rolling out Windows 11 to eligible devices available, but just like every big company, it's also started the entire process of upgrading its very own number of computers to the new operating system.

And more importantly, it managed to complete the procedure in no less than five weeks, with Microsoft explaining that whenever this massive effort was over, no less than 190,000 devices were running Windows 11.

"Introducing a brand new operating-system, especially across a distributed workforce, naturally resulted in questions about device downtime and app compatibility. However, with established practices and evolved solutions at hand, historical obstacles became just that-a subject put to rest. The rollout of Windows 11 at Microsoft was probably the most streamlined up to now, frictionlessly delivering employees the latest operating-system in record time," Microsoft explains.

No app compatibility concerns

The app compatibility would have been a priority, but Microsoft says it relied on App Assure to make sure no such problems occur following the change to Windows 11.

"Data from App Assure, a Microsoft service available to all customers with eligible subscriptions, shows the organization had 99.7 percent compatibility for those apps in Windows 11-that eliminated the need for extensive testing. Additionally, it meant that employees' Windows 10 apps work seamlessly in Windows 11. Additionally, Microsoft Endpoint Manager and Windows Update for Business eliminated the need for exceeding one disk image and made it easier for employees to obtain Windows 11," it says.

The procedure was split into three different plans to plan, prepare, and deploy the new operating-system.
