Microsoft is making a new Canary version of Windows 11 available to Insider testers, with some new features. We invite you to dissect all of this as well as the complete release notes that accompany this new build 27871.
Microsoft is currently pushing a new build of Windows 11 to the Insiders Canary channel. This build, number 27871, comes with a few changes—which should arrive in a future stable update via Windows Update. These mainly include improvements to the Connected Mobile component in the Start menu, new capabilities for IT managers via Microsoft Intune, and a series of stability fixes.
Connected Mobile, now integrated into the Start menu, benefits from grouped notifications for greater clarity. Android users can launch screen mirroring of their smartphone with a single click. For now, this feature remains unavailable for those with an iPhone. However, if you're in the Apple ecosystem, Memories from the Photos app is now supported in this panel—a small consolation.
For businesses, Microsoft Intune adds a rather useful feature that allows you to change a power management-related setting. All this on entire groups of laptops, in just a few clicks. It all happens in the Local Group Policy Editor. It thus becomes possible to activate the “Energy Saver” setting, which then puts all linked machines into this mode. The screen brightness is then reduced, and performance adjusted.
This provides a quick response to battery life issues in fleets of machines intended for company employees. Finally, the update changes a small detail in the interface design. A gray, blue, or red line appears under running applications. This becomes more or less long depending on the attention required by the user.
Here are the full release notes for Windows 11 build 27871 available on the Insider Canary channel now (translated from English):
🌟 General Changes
🛡️ Virtualization-Based Security (VBS)
Fix: VBS sometimes prevented apps that rely on virtualization (e.g., VMware Workstation) from starting unless the optional component "Windows Hypervisor Platform » was installed.
In short: VBS isolates sensitive parts of Windows in a "mini-virtual machine." This fix restores compatibility without having to tinker with Hyper-V components.
