Client/Server Runtime Subsystem

The Client/Server Runtime Subsystem, or csrss.exe, is a component of the Windows NT family of operating systems that provides the user mode side of the Win32 subsystem. In modern versions of Windows, it is primarily involved with process and thread management, console window handling, side-by-side assembly loading and the shutdown process. Historically, it had also been responsible for window management and graphics rendering, however, these operations have been moved to kernel mode starting with Windows NT 4.0 to improve performance. CSRSS instances are marked as critical processes, meaning that terminating one will crash the system, if the critical status is removed and one is terminated, the system will freeze. Built-in process management tools in most Windows versions will also refuse to kill instances of CSRSS. Under normal operation, there is a CSRSS instance for each session (two in Windows Vista and newer, one in earlier versions, both assuming there are no active RDP connections which spawn extra sessions).
