However, in a mixed operating system environment (one in which servers and clients might run on different operating systems), conflicts can occur when client computers run a version of the print driver that is different from the one on the print server. With Windows NT 4.0, print drivers are executed in kernel mode. A kernel mode process runs in a specially privileged part of the operating system that gives the process access to all of the system resources. Consequently, a misbehaving driver can cause serious system stability problems, including operating system crashes. In an effort to increase operating system stability, Microsoft determined that, starting with Windows 2000 and continuing with all future operating systems, print drivers would run as user-mode processes. User-mode drivers execute in a protected part of the operating system just like all of the normal end-user processes and software programs. A user-mode print driver that misbehaves is capable of crashing only the process in which it is running, and cannot crash the whole operating system. Because access to critical system resources is restricted, overall operating system stability is increased.
