It's that time of the month again, folks! Get your update caps ready because it is Microsoft update time.

If you are a regular reader of Komando.com, you should know by now that Microsoft issues a set of cumulative updates once a month. This day, which usually falls on the second Tuesday of each month, is unofficially called Patch or Update Tuesday by tech fans and savvy Windows PC users alike.

It's not exactly a big red-letter day for the tech industry but IT professionals and regular consumers mindful of computer security are always eager to know what each Patch Tuesday brings. These updates usually contain bug fixes, security patches and malware database refreshes for supported Windows operating systems and a slew of Microsoft software products. (Last month, in a surprise move, Microsoft even included emergency patches for unsupported systems like XP and Vista.)

Microsoft patches for July 2017

Microsoft rolled out its July patches for its software products yesterday. These patches include fixes and security updates for Windows 10, Windows 10 Creators Update, Microsoft Edge, Internet Explorer 11, Microsoft Exchange, .NET Framework and a variety of other Windows components. As always, patches for Adobe Flash Player are also included.

A total of 55 security issues, including 19 critical vulnerabilities, ranging from remote code execution, memory corruption and elevation of privilege flaws were fixed in this month's batch of Windows 10 updates.

One flaw in particular, CVE-2017-8584, is already publicly disclosed. This concerns a remote code execution vulnerability in Microsoft's HoloLens. This flaw can let an attacker take control of a system by sending a specially crafted Wi-Fi packet that targets the HoloLens firmware.

The Windows 10 Creators Update patches, KB4025342 (OS Build 15063.483), includes quality improvements but no features are being introduced. Here's its change log:

  • Addressed issue introduced by KB4022716 where Internet Explorer 11 may close unexpectedly when you visit some websites.
  • Addressed issue to improve MediaCreationTool.exe support for Setup Tourniquet scenarios.
  • Addressed issue with CoreMessaging.dll that may cause 32-bit apps to crash on the 64-bit version of the Windows OS.
  • Addressed an issue where Visual Studio or a WPF application may terminate unexpectedly (stops responding, followed by a crash) when running on a pen and/or touch enabled machine with Windows 10 Creators Update.
  • Addressed issue that causes the system to crash when certain USB devices are unplugged while the system is asleep.
  • Addressed issues with screen orientation that stops working after lid close and lid open transitions.
  • Addressed issue that causes .jpx and .jbig2 images to stop rendering in PDF files.
  • Addressed issue where users could not elevate to Administrator through the User Account Control (UAC) dialog when using a smart card.
  • Addressed issue where input using the Korean handwriting feature dropped the last character of a word or moved it to the next line incorrectly.
  • Addressed issue with a race condition between the App-V Catalog Manager and the Profile Roaming Service. A new registry key is available to control the waiting period for App-V Catalog Manager, which allows any third-party Profile Roaming Service to complete.
  • Security updates to Internet Explorer 11, Microsoft Edge, Windows Search, Windows kernel, Windows shell, Microsoft Scripting Engine, Windows Virtualization, Datacenter Networking, Windows Server, Windows Storage and File Systems, Microsoft Graphics Component, Windows kernel-mode drivers, ASP.NET, Microsoft PowerShell, and the .NET Framework.

Microsoft noted one issue with this update -  if you are using a software called Comodo Internet Security Suite and you haven't installed its latest version, this update will not be offered to your machine automatically.

Adobe Flash Update

As usual, security updates for Adobe Flash Player were also released yesterday. July's Flash update includes fixes for a critical remote code execution, an information disclosure bug and a memory address disclosure flaw. Thankfully, none of the flaws are reportedly being exploited in the wild.

How to update Windows

Most Windows machines are set to download and install updates automatically by default. If you haven't changed your automatic update settings then you should be fine.

But if you want to check, here's how:

 

Automatic Windows updates

 

On Windows 10, click Start (Windows logo), choose "Settings," select "Update & Security," then on the "Windows Update" section, click on "Advanced Options." (Note: the "Windows Update" section is also handy for showing you updates that are currently being downloaded or applied.) Under "Advanced Options," just make sure the drop down box is set to "Automatic."

If you have an older Vista or Windows 7 system, check out our tips on how to set up and check Windows Updates.

Update Flash

Adobe Flash updates are included in Microsoft's Windows updates.

For Chrome, Internet Explorer 11, and Microsoft Edge browsers, the updates should be applied automatically after a restart. For other browsers, you may need to update the Flash plugin manually.

The latest Flash Player version for Windows, Mac, Chrome, Microsoft Edge and Internet Explorer 11 and Linux is 26.0.0.137.
