How to Fix iphlpsvc.exe High Memory Usage
The iphlpsvc.exe process is a core part of the Internet Protocol Helper Windows service. It is part of the Windows 10 operating system, and it handles a significant fraction of network configuration management, as well as network-connected devices. The good news is that the iphlpsvc.exe service is not necessary for your network to run properly. This means that it should be safe to stop it in most cases.

However, some users report experiencing iphlpsvc.exe high memory usage. Without any obvious reason, the service ends up taking hundreds of megabytes of RAM. Typically, this should not happen, especially if it is a regular occurrence. However, it is a possible consequence of running a complicated network, or using one too many network devices simultaneously.

The first troubleshooting step should be to try and restart your computer. This should be sufficient to ensure that all services are restarted, and that all network connections get a fresh start as well. Most users report that this fixes the problem for them.
