Microsoft Windows 10 users may often notice a process called “smss.exe” running on their system. You may wonder “What is smss.exe?”. What does it do? Is it a virus?
SMSS stands for session manager subsystem. It handles the launching of the user session on any Windows machine. This process initiates, among other things, the login screen where the user has to enter a password to be able to access the files and programs on the computer.
This process is harmless, and when terminated unexpectedly, can cause the computer to freeze, or even shut down unexpectedly. In rare cases, a virus may masquerade as this process – most antivirus programs can recognise this though, so make sure that your virus protection is always up to date.
