The latest Patch Tuesday update for Windows 11 is the heaviest in recent memory, bringing a new low-latency mode for smoother system navigation in addition to new features and hundreds of bug and exploit patches. This is a much-needed relief package for Windows 11 as Microsoft puts a renewed focus on its flagship operating system, which has suffered a poor reputation among tech enthusiasts over the past several years. The Redmond giant is now dumping the CoPilot button and shipping improvements in performance into long-abandoned areas of UX and OS.
Users will see the June update as KB5094126 (OS builds 26200.8655 and 26100.8655) in Windows Update. The big news here is the low-latency profile, which will help reduce slow loading times when launching core system shell elements like the Start menu, Action Center, and Search, as well as apps. This is a simple trick. When a user clicks to open a system element or app, the CPU immediately reaches its maximum clock speed for a second or three, then jumps back down, giving enough performance headroom to speed up launch. Previously, the CPU needed to ramp up with increased load, which could lead to sluggish launches. While the low-latency profile is included in the June security update, it won’t be turned on for everyone immediately. You can check if it is enabled by viewing a live view of your CPU speed in Task Manager or a third-party tool like HWiNFO64. If enabled, you will see a very brief increase in CPU activity when you open the System Flyaway element mentioned above.
Microsoft has been improving the Start menu over the past few months, and the low-latency profile plays a key role in those upgrades. Mine has been much more responsive lately, whereas before all the improvements, I would often wait a few seconds for it to open. The June update also significantly improved app launch speeds, even on my beefy gaming system. As explained neovinThere are even more upgrades coming in a future public build, including the ability to remove and add each section of the Start menu. You can also turn everything off, so that when the Start menu opens, you only see a notice that says, “All Start sections are closed.” User’s choice? In 2026? pinch me.
Other Windows 11 bugbears have been fixed with this update, including improvements to downloads from the Windows Store. Previously, downloading and installing updates for apps and system components could be extremely slow for many users. That process should now be much faster. Windows Search is now a little faster, as it will start showing results after entering two characters. If you’re someone who likes to launch apps by pressing the Start key and typing, or if you use Search frequently, this is a big improvement.
New features in the June update include multi-app camera support, so you can now be on a Zoom call and take a selfie at the same time. It also brings Shared Audio, which allows Windows to broadcast audio to two Bluetooth LE enabled headphones or earbuds. Plus, you can finally name your user folder however you like when setting up a new Windows install. Finally, if you have a PC with a dedicated AI chip, there are new NPU monitoring tools in Task Manager.
The biggest changes are the ones you’ll never see. Microsoft has fixed a staggering 206 security vulnerabilities, many of which were rated critical or critical, covering threats ranging from privilege escalation and remote code execution to information disclosure and spoofing, among other threats. One patch (CVE-2026-45657) was particularly significant, a kernel-level remote code execution vulnerability with a threat score of 9.8. Microsoft said in a blog post from May that AI is supercharging vulnerability discovery. Both white and black hat researchers are capable of running penetration tests on an inhuman scale, and Microsoft needs to stay ahead of the arms race to keep Windows systems secure.
