We have a different sort of blog post for today. Microsoft has just rolled out an emergency update for Windows 10 users. This includes POS users who are using a Windows operating system.

While most of our customers use our proprietary Linux system, Koronix, there are some who do use Windows. And for those of you reading who are NOT customers, it’s likely that your business runs on Windows if you’re not using Apple devices.

Read below to learn more about the Windows 10 KB5004945 emergency update.

What Is the Windows 10 KB5004945 Emergency Update For?

The Windows 10 update was released to combat a new cybersecurity threat, “PrintNightmare.” Hackers are able to remote into compromised devices, thereby potentially gaining access to confidential personal and financial information.

They can also control local servers through remote code execution. This allows them to install malicious software, edit data, create new user accounts, and release sensitive information.

How Will the Windows Update Work?

The Windows 10 update is a mandatory update for all users. The update contains a patch that will download automatically. Users can simply choose to restart and update each applicable device to start the download and installation.

There are some infrequently used versions of Windows that do require a separate update and patch. Below is the full list of updates.

  • Windows 10 Home, Pro, 21H1, 20H1, 2004 – KB5004945 (the most common)
  • Windows 1909 – Kb5004946
  • Windows 1809 and Windows Server 2019 – KB5004947
  • Windows 1803 – KB5004949
  • Windows 1507 – KB5004950
  • Windows 8.1 and Windows Server 2012 – KB5004954 and KB5004958
  • Windows 7SP1 and Windows Server 20008 R2 SP1 – KB5004953 and KB5004951
  • Windows Server 2008 SP2 – KB5004955 and KB5004959

Can You Manually Update Your System?

Sure. If you don’t see the automated update in your Start bar complete the following steps:

  • Go to Windows Settings → Updates & Security → Windows Update
  • Select “Check for updates”
  • Confirm that a new patch has begun downloading
  • Once complete, click “Restart now”

What Should I Do With My Windows POS System?

Treat your POS devices as you would any other device. Check for automatic updates in the bottom navigation bar. Choose to restart and update all terminals and tablets.

Be sure to complete these updates before or after your hours of operation. Updates may take a substantial amount of time, and you will be unable to complete sales on any terminals undergoing updates. Plan ahead but get it done sooner rather than later since your data and your customers’ data could be compromised.

How Can I Avoid These Issues?

While there are always cybersecurity threats, there are some easy ways to minimize them. For more general advice, check out our blog on cybersecurity tips for small businesses.

For issues such as the “PrintNightmare” attack, it’s helpfult to use a POS system that runs on its own operating system. Most KORONA POS users operate on our Koronix Linux-based OS. This helps keep your devices and data safe from cyber attacks, allowing your business to operate smoothly at all times.
