Windows 11 Build 27965: Everything new, changes, and fixes

Informatec Digital » Windows » Windows 11 Build 27965: Everything new, changes, and fixes

La Windows 11 Build 27965 It comes with changes designed for those who work with the system daily: developers, administrators, and advanced users. Microsoft continues to refine its platform and is taking advantage of this release to introduce an editing tool directly into the terminal and adjust legacy features that no longer fit its roadmap.

Of all that was announced, two decisions stand out: on the one hand, it appears a lightweight, console-integrated text editor called Edit; on the other hand, the .NET Framework 3.5 is no longer included as a pre-installed component (although compatibility is maintained). This is in addition to a redesigned and scrollable Start menu, the integration of Mobile Link within the menu itself, and several fixes that address annoying bugs such as the hidden taskbar or video playback issues.

Key new features coming in Build 27965

This version features adjustments that, while not groundbreaking, do impact the daily experience. For example, the inclusion of Edit as a native tool It's a practical step for those who edit scripts or configuration files without opening full-featured editors like Notepad or heavy IDEs. It's a streamlined solution for quick changes from the Windows Terminal.

In parallel, Microsoft confirms that .NET Framework 3.5 is no longer factory-activated.Support for this doesn't disappear, but the way you get it changes: you'll have to install it manually if an application requires it. This is another step in the strategy to simplify the system and focus efforts on modern technologies, thus reducing the maintenance of legacy components.

There are also improvements in the interface: the Start menu gets a refresh with a scrollable design, making it easier to access more content without breaking the visual coherence. And for those who rely on their mobile device, the Phone Link feature is integrated directly into the menu itself, significantly shortening the path to bridging the gap between PC and smartphone.

Finally, there is room for quality: Fixed the bug where the taskbar was being hidden improperly and a problem affecting video playback on certain devices has been fixed. These types of fixes, while less noticeable, are what make the difference in everyday life.

Edit: a text editor integrated into the Terminal

The star novelty for technical profiles is Edit, the text editor that runs from the command lineWe're talking about an open-source, lightweight tool focused on speed. Just what you need when you're tweaking a script, reviewing an .ini file, or modifying a configuration without leaving the console.

Among its basic functions are: syntax highlighting (key for quick reading), undo history to rewind if something goes wrong, and fine-tuned performance for nimble navigation through text files. It's not intended to replace an IDE or complex editors, but it does cover specific edits with ease.

Its use could not be more direct: just write edit at the Windows TerminalFrom there, you can open and edit the file you're interested in without resorting to Notepad or external tools. This closeness to the console workflow is what makes Edit such a practical addition.

Microsoft's approach with Edit is clear: minimize interruptionsIf you work with PowerShell scripts, CMD batches, or app configurations, having an editor just a command away saves time and reduces the context switching required to open heavy graphical applications.

.NET Framework 3.5: No longer standard, but still available

Another significant move in Build 27965 is that .NET Framework 3.5 is no longer included by default in Windows 11. This doesn't mean it's no longer supported: legacy app support is maintained, but the user (or administrator) will need to add this component when needed.

The underlying reason is strategic. Microsoft is looking for streamline the system and reduce maintenance of obsolete technologies or on the way out, focusing efforts on modern .NET and the toolset that power current development. At the same time, you avoid burdening entire teams with features many will never use.

What if an older app asks for it? You'll be able to Install .NET Framework 3.5 manually When needed. It's the typical component that some enterprise programs or legacy utilities require. The idea is to have it available on demand, not active for everyone from the first boot.

For IT departments, this change implies review images and deployment processes if they had .NET 3.5 as an active dependency. It's also a good idea to document the integration procedure for scenarios where it's still essential.

Redesigned Start Menu and Mobile Link integration

On the interface front, the Start menu becomes scrollable, which helps you navigate content without cluttering your view. It's a setting designed for those who accumulate apps and shortcuts and needed more space without losing order.

The other visible novelty is that Phone Link integrates directly into the menuThis makes the connection between your PC and smartphone more immediate: opening messages, notifications, or transferring basics feels more natural, just a click away from the Windows nerve center.

These design touches are not mere cosmetic changes. Usability improves when you reduce the number of steps to reach what you use every day. And if you do it without sacrificing visual consistency, the experience feels more measured and fluid.

With these kinds of tweaks, Microsoft reinforces the idea that the Start menu should be a live and useful panel, not just a grid of icons. Service integration and improved navigation are moving in that direction.

Bug fixes and quality improvements

Beyond the news, Build 27965 fixes issues that many have been experiencing.. Highlighting the fix for a bug that caused the taskbar to disappear when it shouldn't, a behavior that affected productivity and caused confusion.

It is also solved a failure in video playback This impacted certain users. These types of incidents, although seemingly occasional, have a significant impact on the system's perceived stability, especially on work or multimedia entertainment devices.

Adding corrections of this magnitude is part of continuous improvement: less friction and more reliability when working, playing or simply using the computer normally.

Who is this compilation especially interesting for?

If you move between scripts, automation or administration, Having Edit integrated into Terminal is a small but great victory.. It allows for quick adjustments without breaking the flow or opening external editors, which translates into time saved throughout the day.

For those who maintain older applications, the new feature with .NET 3.5 requires Review dependencies and plan their on-demand installationThe support is still there, but the way it reaches the team has changed, which is key in corporate environments.

And, for the general public, the Scrollable Start menu and Mobile Link integration These are improvements that are noticeable from the first use. Small steps that add up to comfort and accessibility.

Context: Release Pace and Insider Channels

This build is part of a very active update cycle. 279xx branch builds have been landing on the Canary channel recently, and this new Build 27965 follows the line of rapid iterations with changes focused on development, interface and stability.

At the same time, Microsoft keeps two other channels alive with their own branches: Dev and Beta receive builds with cumulative KBs who test features and fixes at a slightly different pace, but synchronized at a calendar level with the general wave of updates.

For the curious user or the professional who tries new things before anyone else, Insider channels are the way to view and evaluate these changes before they reach the general public. However, always with the necessary caution: these are test builds and may include non-final behavior.
