3 update problems you can avoid by using PRTG


PRTG helps you keep track of your entire network to avoid missing updates. IT infrastructures tend to expand over the years with new servers, routers, workstations, and other devices from different manufacturers.

Because they’re added to the network at different times, they often run on different versions of an OS or on different systems. Plus, the same patch or update is not always required for every computer. Avoid these update issues with PRTG.


Errors during installations

PRTG helps you avoid errors during installations. Like backups, many updates are performed at night to prevent them from disrupting a company’s daily business.

However, if errors occur at night, they’re not always detected the next morning. The PRTG automatic update and patch checker keeps system administrators in the know so you can avoid costly errors.


PRTG helps you close security loopholes and avoid security risks due to outdated software. Without an update and patch checker, security loopholes can quickly crop up in the network – and firewalls and antivirus software often provide for little or no defense against network attacks.

PRTG update and patch monitoring helps system administrators keep their systems secure.

3 preconfigured sensors for Windows update checking in PRTG

Windows Updates Status (PowerShell)

The Windows Updates Status (PowerShell) sensor tells you when the last update was performed on an individual device. It also displays the Windows updates that have already been installed and notifies you if updates are missing or critical updates have yet to be installed – all displayed in your dashboard overview.

WMI Security Center Sensor

The WMI Security Center sensor monitors the security status of a Windows client computer via WMI. It can monitor all security products that are controlled by Windows Security Center / Windows Action Center. It will also send you a message if Windows Defender – the Windows virus scanner – is no longer up-to-date.

WSUS Statistics

The WSUS Statistics sensor monitors the Windows Server Updates Services (WSUS) Server, or the server that distributes all Windows updates. It collects and consolidates various statistics on all your devices and provides you with a comprehensive overview. For example, you can see which computers still need updates or where errors have occurred.

Monitor software updates & patches: FAQ


What is patch monitoring?

Patches are offered for operating systems and software. They are usually made available when an error is detected which must be fixed at once. Such errors often include security loopholes. Windows, for example, can offer several patches in one package. Each patch detected by the PRTG patch checker has a different version number.

What is update monitoring?

Updates are also used to optimize programs. But unlike patches, they are scheduled in advance and do not take place at once. Updates (or “upgrades”) are offered when new features become available for a system or piece of software. They therefore upgrade and enhance programs. The program is updated and receives a new version number.

Why should I check for updates and patches?

Checking for updates and patches is crucial for several reasons, primarily related to the security, performance, and functionality of your software, operating systems, and applications. Here are some key reasons why you should regularly update and patch your systems:

  • Developers release updates and patches to fix security vulnerabilities discovered in their software.
  • Updates and patches often include fixes for bugs and glitches present in earlier versions.
  • As technology evolves, software developers update their products to ensure compatibility with the latest hardware and operating systems.
  • Updates often introduce new features, enhancements, or improvements to existing functionality.
  • Updates may include security measures to protect your data.
  • Software vendors typically provide support for the latest versions of their products.

How does checking updates with PRTG work?

A sensor scans your operating systems for their current version, then inquires online as to the most current version available. If the two do not match, you will be notified or an update will be arranged. An example: PRTG includes the preconfigured Windows Updates Status (PowerShell) sensor so you can be sure your Windows OS is always up-to-date.

What is a sensor in PRTG?

In PRTG, “sensors” are the basic monitoring elements. One sensor usually monitors one measured value in your network, for example the traffic of a switch port, the CPU load of a server, or the free space on a disk drive.

On average, you need about 5-10 sensors per device or one sensor per switch port.
