What to do before taking action
What happens if you REMOVE smss.exe? (New Year's Special)
Launch Task Manager on your Windows PC and you will see a number of system processes running in the background. Normally, there is no reason to care about these files and processes, what they do, or to question their safety unless they are affecting the performance of your PC.
Even if a strange background process that behaves oddly catches your attention, it can be difficult to determine whether it is safe. A system process like smss.exe is often associated with unreasonably high CPU and GPU usage. In this guide, we will explain what smss.exe does and how to check if you have a safe version of the file on your computer.
smss.exe is the executable file responsible for running the Session Manager Subsystem (or Windows Session Manager). It is an important component of the Windows operating system that runs immediately when you click the power button. It is responsible for creating user sessions and monitoring other crucial system processes to ensure that they are working properly.
