Microsoft has pushed out one of the biggest Windows 11 updates in recent memory, and this one does more than patch holes. The Windows 11 KB5094126 release, tied to builds 26200.8655 and 26100.8655, adds a low-latency mode that briefly cranks up processor speed to make stubborn parts of the interface feel less sluggish, while also delivering new features, hundreds of fixes, and 206 security patches.
The headline trick is simple enough: when you open Start, Notification Center, or Search, Windows temporarily raises CPU frequency to maximum, then drops it back down. In other words, Microsoft is trying to make the OS feel fast where people actually notice lag, instead of bragging about benchmarks nobody lives in. The feature will not be enabled for everyone right away, and users can check its status in Task Manager or specialist tools.
Windows 11 Start menu and Store get speed upgrades
Microsoft is also tightening up the parts of Windows 11 that people poke at all day. The Microsoft Store should now download and install apps faster, while Search starts surfacing results after just two typed characters. That sounds like a small tweak, but for a system that has often felt one step behind its own hardware, small wins are exactly the point.
There are a few quality-of-life extras too: multiple apps can now share the camera at the same time, so you can be on Zoom and snapping a selfie without the usual app tug-of-war; Bluetooth LE audio can now play to two pairs of headphones at once; and the user folder can be renamed more freely. Task Manager also gets new NPU monitoring tools, though only machines with an AI accelerator will see them.
Windows 11 security update closes 206 vulnerabilities
The security side is doing the real unglamorous work here. Microsoft says the update closes 206 Windows vulnerabilities, including serious and critical ones. One flaw, CVE-2026-45657, carried a 9.8 out of 10 rating and could have allowed remote code execution at kernel level, which is about as bad as it sounds.
What stands out is the mix: performance polish, a few consumer-facing features, and a large security haul in one package. That is often how Windows updates work when Microsoft wants to make the system feel both safer and less annoying at the same time. The more interesting question is whether the low-latency trick becomes a quiet default for more people in the next builds, or stays hidden as one more Windows feature only power users will ever notice.
