Do you want projectors, printers or other media devices to be recognized directly by your computer? This is where the "Simple Service Discovery Protocol" comes into play. You can use SSDP to search for such UPnP devices on your network. SSDP comes from Microsoft and, as a multicast search service, can send audio and video content to multiple devices in your network at the same time. For more information on SSDP and instructions on how to disable the service, read this post.
What does SSDP mean?
The "Simple Service Discovery Protocol" (SSDP for short) is basically nothing more than a search service for so-called UPnPs. A UPnP (Universal Plug and Play) is a standard that ensures that devices can communicate with each other - for example when you plug a USB stick into your computer. Other such UPnP devices are, for example, printers, routers, audio devices and smart home controls. SSDP comes into play when you are looking for such devices on your network. In order to be found by SSDP, the UPnP must also use the SSDP search protocol. An example: You want to share video files for the XBox 360 on your PC - in this case SSDP must be active. If you stop the SSDP service on your device, SSDP-based devices will no longer be recognized until the next start.You can also disable the service to prevent any SSDP-dependent devices from starting.
How to disable the SSDP search service
On some systems, the SSDP search service in conjunction with svchost.exe (for executing Windows services) causes significantly higher CPU loads. It can therefore be helpful to deactivate the service. In our step-by-step guide , we'll show you how to do it. In the brief instructions you will find the individual steps again in a summarized form..
1st step:
Start the control panel of your PC and select " System and Security ".
