The latest Patch Tuesday update for Windows 11 is among the heaviest in recent memory, bringing a new low-latency mode for smoother system navigation in addition to new features and hundreds of bug fixes and exploits. It’s a much-needed fallback program for Windows 11 as Microsoft puts renewed emphasis on its flagship operating system, which has fallen into disrepute among tech enthusiasts in recent years. The Redmond giant is now ditching Copilot buttons and making UX and performance improvements to long-abandoned areas of the operating system.
Users will see the June update as KB5094126 (OS versions 26200.8655 and 26100.8655) in Windows Update. The big news here is the Low Latency Profile, which should help alleviate slow loading times of basic system shell elements like the Start Menu, Action Center, and Search, as well as when launching applications. It’s a simple trick. When a user clicks to open a system item or application, the processor immediately jumps to its maximum clock speed for a second or three and then drops back down, providing just enough performance headroom to speed up the launch. Previously, the CPU had to increase with increased load, which could exacerbate slow launches. Although the Low Latency Profile is included in the June security update, it will not be enabled immediately for everyone. You can check if it’s enabled by watching a live view of your CPU speed in Task Manager or in a third-party tool like HWiNFO64. If this option is enabled, you will see a very brief spike in CPU activity when you open a system flyout like the ones mentioned above.
Microsoft has been making improvements to the Start menu for a few months now, and the low latency profile is rather the cornerstone of these upgrades. Mine has been a lot more responsive lately, whereas before all the fixes I would often wait a few seconds for it to open. The June update also brought a noticeable improvement to app launch speeds, even on my rather beefy gaming system. As explained NeowinThere are even more upgrades coming in a future public release, including the ability to remove and add each section of the Start menu. You can even disable everything, so that when the Start menu opens, you only see a notice that says “All startup sections are disabled.” User choice? In 2026? Pinch me.
Other Windows 11 bugs have been fixed with this update, including improvements to downloads from the Windows Store. Previously, downloading and installing updates for applications and system components could be extremely slow for many users. This process should now be much faster. Windows Search is now also a little snappier, as it will start showing results after two characters are entered. This is a big improvement if you’re the type of person who likes to launch apps by pressing the Start key and typing, or if you use search frequently.
New features in the June update include support for cross-app cameras, so you can now join a Zoom call and take selfies at the same time. It also brings Shared Audio, which allows Windows to stream audio to two Bluetooth LE compatible headphones or earbuds. Plus, you can finally name your user folder whatever you want when setting up a fresh installation of Windows. Finally, there are new NPU monitoring tools in Task Manager, if you have a PC with a dedicated AI chip.
The biggest change is the one you will never see. Microsoft has patched a staggering 206 security vulnerabilities, many of which have been rated critical or severe, with threats ranging from privilege escalation and remote code execution to information disclosure and identity theft, among others. One patch (CVE-2026-45657) was particularly critical, a kernel-level remote code execution vulnerability with a threat score of 9.8. Microsoft said in a blog post published in May that AI is boosting vulnerability discovery. White and black hat researchers are capable of performing penetration testing on an inhuman scale, and Microsoft must stay ahead in this arms race to keep Windows systems secure.
