In March, Windows president Pavan Davuluri confirmed plans to address serious “paint spots” across Windows 11 that eroded user trust and created a wave of negative feelings around the OS, caused by Microsoft’s relentless push for AI and prestige while neglecting Windows basics like performance and reliability.
Of course, what Microsoft says on the outside doesn’t always reveal what it thinks on the inside, but in this case, my sources say the company. is something serious about turning Windows 11 into a platform people are proud to use. By the end of 2026 to 2027, Microsoft strives to have Windows 11 in the best place.

Performance, Creativity, and Reliability
These are the three main focus areas of the Windows K2 system.
These pillars are what drive the Windows experience. If one of these pillars falls behind, the entire product suffers as a result. With Windows K2, Microsoft is working to ensure that these three pillars are strong by addressing feedback directly from users and insiders, analyzing telemetry data, and conducting focus groups with customers.
I am told that K2 is also looking within the groups themselves. It’s not just about addressing feedback and fixing Windows 11, but also about how teams within can better contribute code to the Windows product. I understand that there is a huge culture change going on inside right now that is driving the K2 campaign.
In the past, Windows was thought of as fast. It was eager to ship new features as quickly and as often as possible, but this ultimately came at the cost of quality and reliability. While teams are able to release new features quickly, users are frustrated with an OS that is not stable and is becoming more and more problematic.
One of the biggest culture changes internally that I’ve heard about is that teams are no longer trying to ship quickly. The obsession with speed has been replaced by an obsession with quality. I understand that new features are not allowed near public preview builds before reaching a certain quality bar internally now, and while that bar has always been there, the bar is much higher now.
There is a little-known fourth pillar, too: Community. The Windows K2 initiative is eager to rebuild the community of Windows fans and enthusiasts. Brings back Windows Insider meetings, and assigns Windows team members to look forward to social media and forums to directly respond to feedback from people online.
Performance and Reliability
Performance is a priority in the Windows K2 effort. In documents viewed by Windows Central, Microsoft is known to have enabled smooth operation in programs such as File Explorer and games, as well as system UI elements such as context menus. Windows 10 is often found to be faster than Windows 11 in some benchmarks, and the company is moving to change this.
In terms of gaming, Microsoft views steamos as a benchmark, and is working to improve the platform so that steamos and Windows game performance can be compared. During the next year or two, it is believed that Windows will be able to really compete with steamos in game performance on the same hardware due to the fundamental changes made to the platform in the coming months.
File Explorer is set to receive major performance improvements, speeding up file navigation and processing, and improving search speed within the File Explorer app, with capabilities such as “quick file name search” coming. The company is looking at a third-party app called File Pilot as a benchmark for this development.
Windows Update will also be improved, with the aim of making Windows 11 reliable enough that a reboot is required once a month. Under the hood changes are also expected designed to make Windows updates more seamless, such as only updating the display and audio drivers upon restart instead of active usage.
I’m told there’s a concerted effort to roll out Windows 11 as well, focusing on reducing idle memory usage and shrinking the overall OS area to make it work better on low-end hardware and smoother on high-end apps and gaming handhelds.
Craft and UI
Craft is also a major focus area for K2, addressing user experience complaints and bringing back fan favorite features that were missing from the original Windows 11. Microsoft has already confirmed plans to bring back the ability to move and resize the Taskbar, one of Windows 11’s the majority requested features.
The K2 system also pressures teams internally to rely heavily on its internal Windows UI framework. WinUI 3 is the foundational part of K2, with performance improvements in the works to ensure that these native UI environments are faster and more reliable for use in many areas of the system, including where legacy links currently exist such as Run and Control Panel.
One of the ways I’m told this is possible is the new System Compositor for WinUI 3, which will reduce latency and memory overhead across the UI so things like the Start menu and Taskbar stay responsive and available for use, even under heavy system load.
In fact, with this new composer in place, Microsoft is rebuilding the Start menu from scratch with WinUI 3 naturally. I’m told that this new Start menu will be up to 60% faster and more responsive than the existing one, while it will also sport customization options such as the ability to resize and hide parts of the menu.
The K2 project also faces some of the biggest issues around encryption. I’m told Microsoft is removing ads from the start menu, which is no small feat from a financial standpoint. It also plans to stop MSN from automatically appearing in the Widgets Panel, instead putting the Widgets Panel first and MSN as the second task instead of the first.
K2 is changing
Windows K2 does not have an end date. It’s an ongoing process that defines exactly how Windows should be built and what should be prioritized going forward. The goal is to fix Windows 11 and reposition the platform as something people are proud to use, and maintain that consistently.
It’s a great move that Windows desperately needs, and it helps position the platform as a viable competitor in the future. The changes and improvements that are part of the Windows K2 program have begun to ship, with many other shipments seen first in the summer.
