Client/Server Runtime Subsystem
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 and is included in Windows NT 4 and later.
Malware hoaxes
There are numerous virus hoaxes that claim that csrss.exe is malware and should be removed to prevent damage to the system- these are false, as removing csrss.exe or killing the csrss.exe process will result in a Blue Screen of Death.
History
The Windows NT 3.x series of releases had placed the Graphics Device Interface component in CSRSS, but this was moved into kernel mode with Windows NT 4.0 to improve graphics performance.[1] The Windows startup process has changed significantly since Vista. Two instances of csrss.exe are running in Windows 7 and Vista.[2]
