If it feels like everything needs a patch lately, you’re not imagining it.
For IT professionals, patching is nothing new. Microsoft’s “Patch Tuesday” has been a fixture of IT for more than two decades. Operating systems, browsers, business applications, firewalls, network equipment, and countless other technologies have always required regular security updates.
But in the last three months, things have escalated dramatically.
Breaking Records
In June 2026, Microsoft released what was, at the time, its largest Patch Tuesday ever, addressing roughly 200 vulnerabilities.
That record lasted about a month.
In July, Microsoft’s security release addressed 622 vulnerabilities across its products: more than 400 affected Windows, dozens were rated critical, and two vulnerabilities were being actively exploited.
August wasn’t much better with about 400 vulnerabilities.
Patch Tuesday releases containing 100 vulnerabilities were once considered unusually large.
What changed?
Microsoft Told Us This Was Coming
Microsoft announced in July that it now increasingly uses AI to accelerate vulnerability discovery. The company developed new technology that uses multiple AI models to examine critical software, identify potential vulnerabilities, and validate findings. Additional Windows-specific processes reduce false positives. Human experts remain responsible for reviewing everything and making security decisions.
Microsoft was unusually direct about what this means for customers: expect more security updates in each release.
More Patches Doesn’t Necessarily Mean Worse Software
Hundreds of vulnerabilities in a single month sounds alarming.
But imagine turning on brighter lights in an old warehouse and suddenly noticing dozens of cracks. The lights didn’t create the cracks. They just made them easier to find.
AI is doing something similar with software.
Modern operating systems and business applications contain enormous amounts of code, including components developed over decades. AI-assisted tools can examine that code at a scale and speed that would be difficult for human
researchers alone.
That means some of today’s “new” vulnerabilities are not actually new at all.
We are simply getting much better at finding them.
There’s Another Side to the AI Equation
Unfortunately, attackers also have access to AI.
They can use the same advances to analyze software, research vulnerabilities, automate reconnaissance, and potentially develop exploits faster. Once a vulnerability becomes known and a patch becomes available, attackers can begin studying what changed. Organizations that delay updates may leave documented weaknesses available for exploitation.
The takeaway: timely patching is increasingly important.
More Patches Also Means More Opportunities for Something to Break
But the challenge isn’t simply “patch faster”. It’s “patch better”.
The fact is that updates occasionally cause problems. A patch can conflict with an application, change a configuration, affect a driver, create a performance issue, or cause an unexpected problem with a business-critical system.
Now multiply that possibility across hundreds of fixes, dozens of applications, servers, endpoints, cloud services, and network devices. That’s why businesses need a process to identify what needs attention, test updates where appropriate, deploy them in a controlled way, and monitor results.
Waiting too long creates cybersecurity risk, but deploying everything blindly creates operational risk.
Good patching manages both.
There’s Another Side to the AI Equation
Businesses should expect higher patch volumes as AI improves software companies’ ability to discover security weaknesses.
But more patches don’t automatically mean technology is less secure. It could mean we’re becoming better at finding problems previously unnoticed.
That’s a good thing, but it does change the job for IT.
In a world where AI can uncover hundreds of vulnerabilities in a matter of weeks, businesses can no longer install updates whenever they get around to it.
