You may have come across the mayday situation when your Windows PC is freezing. Then you open Task Manager to find out the reason, and some background services called svhost.exe are running and consuming lots of resources, like 80% Memory usage.

What is svhost.exe? You do not even know where to open the program, how dare they run secretly and eat most of your computer resources? No worries, here are the answer and the solutions to fix them.

What is svhost.exe?

Svchost.exe is a generic host process name for services that run from dynamic-link libraries. In other words, Svchost.exe is a process on your computer that hosts, or contains, other individual services that Windows uses to perform various functions. Services are organized into logical groups that are all somewhat related, and then a single Service Host instance is created to host each group. That’s why you see so many Service Host Processes running in the background—they are doing their job!

However, in certain cases, you may see svchost.exe process hogging the CPU or memory resources in Task Manager without apparent reasons.
