This can be a cause for concern for some users, as the name may sound unfamiliar and potentially malicious. In this article, we will explore what lsass.exe is, its purpose, and whether or not it should be removed from your system.
Understanding lsass.exe
Lsass.exe, which stands for Local Security Authority Subsystem Service, is a legitimate Windows process that plays a crucial role in the security and authentication of your operating system.
