PC users get their turn too. Microsoft’s November 2025 Patch Tuesday is out and it’s smaller than October’s huge wave, but it still fixes 89 vulnerabilities across Windows, Office, Exchange and other products — including a few that are already being exploited. If you use your PC for work, accounting or online payments, install this one now.
What Microsoft is pushing this month
- Cumulative updates for Windows 11 (and supported Windows 10 builds)
- Security fixes for Office and some server products
- Cleanup after October’s very large patch wave
- A continued path toward the newer, slimmer Windows support lineup Microsoft talked about this fall
Why it still matters even if it’s “smaller”
- 89 vulnerabilities is not small — it’s just smaller than last month
- Some of the fixes are for issues attackers are already trying to use
- Updating now means you don’t carry October leftovers + November issues together
How to update safely
- On Windows → Settings → Windows Update → Check for updates
- Let Windows download and install the November security rollup
- Reboot once
- If you manage multiple PCs, run the same update today so everything is on the same patch level
Things admins and power users should note
- October 2025 was huge because a lot of older Windows/Office items were reaching end-of-life; November is calmer, so it’s a good month to catch up machines that missed last month.
- Windows Server 2025 also has its update history live — grab the latest one to stay current.
- Microsoft is keeping to its “second Tuesday” cadence, so December will come quickly — staying current now makes December easier.
Quick checklist
✓ Windows Update shows a November 2025 cumulative update installed
✓ PC rebooted
✓ Office/security apps still run
✓ No pending restarts
If that matches your PC, you’re done for this month — and you’re not carrying unpatched November 2025 bugs.
