Microsoft is persistently fortifying its strategy of pre - installing apps on Windows 11. The latest revelation is that for users who've already got Microsoft 365 desktop apps installed, the Microsoft 365 Copilot app will be automatically pre - installed. Being an integral part of the Microsoft 365 suite, this app will seamlessly integrate into the Windows 11 system, offering office functions with the aid of artificial intelligence. This step is in line with Microsoft's approach of pre - installing full - version apps, which was first put into action in the Windows 11 24H2 version starting from June 2025. The ultimate goal of this strategy is to elevate user experience and bolster security. The Microsoft 365 Copilot app is projected to commence its rollout in the autumn of 2025. However, it will exclusively support the Windows 11 system and won't be accessible to Windows 10 users.
