400+ Windows Bugs Fixed: What NJ Businesses Must Do Now

400+ Windows Bugs Fixed: What NJ Businesses Must Do Now

400 bugs is not a typo

When Microsoft patches over 400 security vulnerabilities in a single update, that's not routine housekeeping. That's a signal that attackers have been busy, and that your Windows 11 machines are sitting exposed until those patches land. Microsoft flagged this one as urgent, which means some of the vulnerabilities are actively exploited or close to it.

For a small business in New Jersey running five to fifty Windows machines, the math is simple. Every unpatched PC is a potential entry point. Ransomware groups don't care whether you're a law firm in Hoboken or a distributor in Edison. They scan for known vulnerabilities and hit whatever's open.

Why "we'll get to it" doesn't work here

I've seen this pattern more times than I'd like to count. An owner gets a vague notification that Windows needs to update, dismisses it, and forgets about it. Three weeks later, something breaks or something worse happens. The update was sitting there the whole time, uninstalled.

Microsoft's three-day warning isn't marketing language. When they push that kind of timeline, it usually means there's a known exploit in the wild or one is expected imminently. Waiting until the weekend to "let it run overnight" is too long in that context.

If you have Windows Update for Business or Intune managing your fleet, now is the time to check your deferral settings. A lot of IT policies defer updates by 7 to 14 days to avoid disrupting production. That's normally reasonable. For a patch release like this one, you want to override that deferral and push immediately.

What to actually check right now

First, find out which machines in your office are running Windows 11. Go to Settings, then Windows Update, and look at what's pending. If you see the August 2026 cumulative update listed and it hasn't installed, start it now.

Second, if you're using Microsoft Intune or a third-party RMM tool like NinjaOne or ConnectWise, pull a compliance report. You want to see which devices are patched and which aren't. Any machine that hasn't checked in recently is a blind spot.

Third, don't forget the machines that aren't in the office. Remote workers, traveling salespeople, anyone on a laptop that mostly connects from home. Those devices often miss patches because they're never on a corporate network long enough to sync. If you're managing those through Intune or a VPN-connected policy, verify they're receiving updates too.

One more thing. Restarting the machine actually matters. Windows will download an update and sit there waiting for a reboot indefinitely. A machine that shows "update downloaded" is not the same as a machine that's patched. The fix isn't applied until the system restarts.

What this means if you're still on Windows 10

Windows 10 support ends in October 2025, and we're past that now. If you've got machines still running Windows 10, they're not receiving security updates at all unless you're paying for Microsoft's Extended Security Updates program. That's a real cost and a temporary fix. The actual answer is upgrading those machines to Windows 11 or replacing hardware that can't run it.

I know hardware refreshes aren't free. But running an unpatched, unsupported OS in a business environment is a liability, not just an IT problem. Cyber insurance carriers are starting to ask about patch status during renewals. Some are denying claims when breaches happen on machines that were known to be out of support.

Build a process, not a one-time fix

Chasing down patches manually every month isn't scalable. If you have more than ten machines, you need a centralized way to see patch status across all devices and push updates on a schedule you control. That's what tools like Intune and Windows Update for Business are built for. Set them up correctly once, and you stop having to wonder whether your machines are current.

If you're not sure where your business stands on patch compliance right now, Exine works with small and mid-size businesses across New Jersey and New York to get that visibility in place and keep it there.
