Key notes

The Nissrv.exe process runs in the background and launches automatically when your computer boots up. It ensures security in your device remains upheld, but some users are having issues with the performance of their devices dropping.

If you’re one of these people with anoverheating PCandrandom shutdowns, you may want to pump the brakes first before you disable it, and here’s why.

What is Microsoft Network Realtime Inspection Service?

Microsoft Network Realtime Inspection Service is a built-in Windows service that runs in the background of your PC. It is used to check for and block malicious content such as viruses, spyware, and hackers.

This service ensures that your computer is protected from threats byanalyzing network trafficfor specific security threats and blocking them if found. It helps protect your PC from security threats by intercepting and inspecting all incoming and outgoing network traffic.

The service integrates with Windows Firewall toblock unauthorized access to your computerby Internet users or programs.

You may wonder whether it is necessary, especially since you already have Windows Defender. Well, it is. The nissev.exe file is important as it adds an extra layer of protection, and in these times of advanced security threats, we could all use the extra protection.

Some of the benefits you’ll get from the service include:

Where is the NisSrv exe file?

Since it is a Windows file, you’ll most likely find it in either of the following locations, depending on your Windows version:C:\Program Files\Microsoft Security Client\NisSrv.exeorC:\Program Files (x86)\Microsoft Security Client\NisSrv.exe

The file’s location should provide you with more insight into whether it is a malicious file that somehow found its way to your PC. This could be through downloading programs from untrusted sources or a virus changing things around.

Some common problems users had with the nissrv.exe file were performance issues. For instance, from this thread on the Microsoft Windows forum, a user had many issues.

I have an issue with Windows 11 Defender : Microsoft Network Realtime lnspection Service.exe uses 100% of my GPU. It causes my PC to overheat and to shut down because of heat.

The biggest downside to having a program like this running on your computer is that it’s difficult to disable or uninstall unless you know what you’re doing.

Even if you delete the executable file, there’s no guarantee that it won’t just re-install itself as soon as your next scan is scheduled. This has been a common result for most users who went with this route, so let’s look at other viable solutions.

How do I turn off Microsoft Network Realtime Inspection Service?

We recommend that you check the following first before any technical troubleshooting :

1. Use Windows Security

Observe how your PC behaves, then turn it back on. Operating a system unprotected could expose you to risks so ensure it is not turned off for long periods of time.

2. Uninstall recent Windows updates

This step is mostly for users of the Windows Insider program. Since their systems are less stable than others, uninstalling the update until it has been stabilized could help minimize GPU consumption by the nissrv.exe process.

3. Update your graphic drivers

Remember that you don’t have to go through the manual process, as there is an easier way like a third-party tool designed for the job.

This powerful utility will scan, download, and install the correct driver from its extensive database of 18 million driver files.
