Windows 11 adds a new secure mode that blocks sketchy apps and drivers

Microsoft’s New Windows Baseline Security Mode Aims to Stop Sneaky Software Before It Even Starts

In an era where cyber threats are evolving faster than ever, Microsoft is rolling out a bold new layer of defense for Windows 11 users. Meet Windows Baseline Security Mode, a feature designed to clamp down on risky software—especially the kind that hides behind drivers and background services—before it can dig its claws into your system.

This isn’t just another security patch. It’s a fundamental shift in how Windows decides what gets to run and what gets blocked. By turning integrity safeguards on by default, Microsoft is making code signing the new gatekeeper. If an app, service, or driver isn’t properly signed, Windows can now stop it cold. And while that might sound restrictive, there’s a safety valve: users and IT admins can still approve exceptions when a legitimate tool gets caught in the net.

But the story doesn’t end there. Microsoft is also pushing User Transparency and Consent, a set of prompts that will make Windows speak up when software tries to access your device or data. Whether it’s an app reaching for your microphone, camera, or files—or an installer trying to bundle extra software you didn’t ask for—Windows will now ask for permission. And unlike some past prompts that felt like nagging, these decisions won’t be permanent. You’ll be able to revisit and change them later.

Baseline Security Mode Changes What Can Run

The real game-changer here is how Windows is making low-level changes harder to slip in quietly. Drivers and services are powerful—they can live deep in the OS and survive reboots, which makes them attractive targets for attackers and a nightmare to remove once embedded.

With these new safeguards enabled, code signing becomes the front line. That should dramatically cut down on silent installs of kernel drivers, system services, or helper processes that hook into other apps without your knowledge. It’s a move that could make life much harder for malware that relies on persistence and stealth.

And for those worried about breaking compatibility, Microsoft has built in flexibility. If a trusted app gets blocked, you or your IT admin can grant an exception for that specific case. Developers, too, will be able to detect when protections are active and whether an exception exists—reducing the usual troubleshooting fog that comes with security updates.

The Consent Prompts Are the Other Half

Baseline mode isn’t only about blocking code—it’s also about making behavior easier to see. Microsoft wants Windows to speak up when software tries to use things people actually care about, like the mic, camera, and files.

That matters because a lot of bad experiences aren’t classic malware. It’s installers that bundle extra stuff, apps that grab permissions they don’t need, or tools that change settings without making it obvious. Clear prompts, plus the ability to revisit choices later, makes that harder to hide.

For businesses, the same controls could mean fewer surprises across managed PCs, while still leaving room to approve older software that’s important to operations.

What to Watch Next

Microsoft describes this as a phased rollout, starting with more visibility into app and agent behavior, plus tools and APIs so developers can adapt. Later comes broader enforcement through Baseline Security Mode and the consent experience.

Your best next step is to watch Settings for new review controls, and watch driver makers and security vendors for updated guidance. If you rely on niche peripherals, that’s where friction tends to show up first.
