According to Neowin, Microsoft’s latest Windows 11 Insider build for the Dev and Beta channels, specifically build 22620.7344 under KB5070316, includes a pile of new features. More importantly, a change from a previous November build, 26220.7070 under KB5070300, is now getting more attention. That change removes the mandatory clean installation requirement for enabling Smart App Control, a Windows 11-exclusive security feature introduced in 2022. Microsoft now says users can simply switch SAC on or off via Windows Security > App & Browser Control settings without wiping their PC. The company claims this cloud-based tool not only blocks harmful apps proactively but also has a lighter performance impact than traditional antivirus, potentially helping lower-resource PCs run better. This update is still in testing, with a general availability likely early next year.
Why This Clean Install Rule Was So Annoying
Here’s the thing: that clean install mandate was a massive barrier. It basically meant that if you did a standard in-place upgrade from Windows 10 to 11, you were locked out of this feature permanently unless you nuked your entire system and started fresh. For a security tool pitched as a core Windows 11 advantage, that was a bizarre and user-hostile gate. It sent a mixed message: “This is important for security and performance, but we’re only going to let the most dedicated users have it.” It felt less like a technical necessity and more like an artificial carrot to push clean installs, which Microsoft often recommends for stability anyway. So dropping this requirement is a huge, and frankly overdue, usability win.
Performance Claims and the Bigger Picture
Now, the performance angle is interesting, right? Microsoft is directly positioning this as a lighter alternative to traditional anti-malware. The logic makes sense on paper: blocking apps before they run means less constant scanning and system interrogation. But I think we have to be a bit skeptical. How much of a real-world difference will most people see? Gamers with high-end rigs? Probably nothing. But on an older laptop or a budget educational device, any reduction in background strain is welcome. This feels like part of a larger, quiet push from Microsoft to integrate and streamline security into the OS itself, making it less of a third-party bolt-on and more of a seamless, efficient layer. If they can make security *feel* invisible while being effective, that’s a win.
What Happens Next?
So, it’s in testing. The next real milestone is when this change hits the Release Preview channel—that’s usually the final stop before a full public rollout. An early 2024 release seems like a safe bet. The bigger question is strategic: does this make Windows 11 more appealing to the holdouts still on Windows 10? Removing a friction point helps, but one feature toggle isn’t a killer argument. It does, however, signal that Microsoft might be listening to feedback about overly complex requirements. And in the world of Windows, that in itself is news. Basically, they’re making a good feature easier to use, and that’s always a step in the right direction.
