Windows 11 just got its biggest security update ever: 206 patches, three zero-days, and a CPU trick that actually works

Two hundred and six. That's how many security vulnerabilities Microsoft patched this month—a number so large that even the security researchers counting them couldn't agree on it at first. Some said 198. Turned out the difference was a rounding argument over which bugs counted. Either way: record broken, by a distance.

Three of those flaws were zero-days, which in plain English means the details were already floating around publicly before Microsoft fixed them. One could hand an attacker full system privileges. One could take down a server over HTTP. The third—arguably the most unsettling—lets someone with physical access to your laptop pull data straight off a BitLocker-encrypted drive. You know, the encryption that's supposed to make that impossible.

AI Is why patch Tuesday keeps getting bigger

Here's the uncomfortable context: the reason these patch counts keep climbing isn't that Windows is getting worse. It's that AI is getting better at finding bugs. Microsoft has been using AI-assisted tools to comb through its own code, and so have independent researchers—and so, presumably, have people with less noble intentions. Mozilla patched 271 Firefox flaws in April. Security firm Action1 said the quiet part out loud: AI is surfacing vulnerabilities faster than the industry has ever seen. Patch Tuesday will keep growing.

The Start menu Is Finally Fast. In 2026.

Buried under the security news is something Windows users have wanted for years. Low Latency Profile—the least exciting name for a genuinely useful feature—makes your CPU spike to maximum speed the instant you click the Start menu, Action Center, or launch an app, then immediately back off. It sounds like a fudge because it is one. It also works. Shared audio, multi-app webcam support, and a two-character search trigger round out an update that, for once, has more going on than just staying secure.
