Microsoft Patch Tuesday: Update now to fix a zero-day flaw

November’s Patch Tuesday has arrived for Windows users, and the latest batch of security updates is now available for all supported versions of Windows 10.

This time around, the patch includes several back-end security fixes that protect Windows 10 from cyberattacks. Whether the update breaks things remains to be seen. Tap or click here to see what the last Patch Tuesday update screwed up.

Microsoft’s track record for stable updates has been mixed this year. That said, there are enough security fixes in this Patch Tuesday update to make it worth installing. We’ll show you how.

November Patch Tuesday update addresses zero-day issues and back-end flaws

Microsoft is offering new updates for Windows 10 as part of November’s Patch Tuesday release. The updates, labeled KB 4586781 and Builds 18362.1198 and 18363.1198, are now available for users to download and install.

The updates don’t add any new features, but they do include several under-the-hood security enhancements to protect against zero-day exploits and bugs:

  • Security updates for Microsoft Office products.
  • Security updates for basic Windows operations.
  • Fixed a 2020 DST bug for the Fiji Islands.
  • Security updates to the Microsoft Scripting Engine, Windows Input and Composition, Microsoft Graphics Component, the Windows Wallet Service, Windows Fundamentals, and the Windows Kernel.
  • Security updates for input devices like keyboards, pens and mice.
  • Security fix for an issue with Windows’ package frame launcher (PSF).

Microsoft hasn’t said if hackers are exploiting any of the security holes it fixed in the wild. To stay on the safe side, you should update your PC sooner rather than later.

To install the update, turn your PC on and open the Start Menu. Then, click on the Settings icon, followed by Update and Security.

If the patch hasn’t already been installed on your PC, you’ll see one of the following updates available for you to download:

  • KB 4586781
  • Build 18362.1198
  • Build 18363.1198

If nothing is available to download, your computer may have already updated in the background. Automatic Updates may have installed the patch for you.

Before you jump in and update, back up all your essential files. If there is a mishap, you could end up losing your data and have no way of recovering it. Don’t start an update until you’re 100% sure you’ve saved everything you need.

Better luck next time? Microsoft working on a fix for annoying Outlook bug

Recently, Outlook users have complained of a glitch that causes deleted emails to reappear in account inboxes. Microsoft hasn’t found the exact cause behind the bug but says that it’s working on a fix for a future update.

The cumulative Patch Tuesday update does not include any fixes for this bug. Still, Microsoft has a workaround for affected users: visiting the original inboxes of email accounts affected by the Outlook bug.

If you use your Gmail account with Outlook, Microsoft suggests visiting and deleting the email there manually. The account should then sync to Outlook without issue.

Microsoft also mentions a workaround for a similar Outlook bug that causes images to display incorrectly. Microsoft recommends that users who receive emails with corrupted images ask the original sender to attach the picture instead.

This bug is currently under investigation as well.

Hopefully, we’ll get these bug fixes in time for next month’s Patch Tuesday. A simple workaround is fine, but it’ll be a pain if we have to do it for longer than a month.
