System idle process | SIP | A counter which measures how much idle capacity the CPU has at any given time. The process runs in the background and monitors processing bandwidth, occupied memory and the Windows virtual paging file. |
Session Manager Subsystem | SMSS | Performs several critical boot-time operations, such as the creation of environment variables, starting CSRSS, and performs file-copy operations that were queued up from before the system was booted (pending file rename operations).

Client/Server Runtime Subsystem | CSRSS | User-mode side of the Win32 subsystem. Provides the capability for applications to use the Windows API. |
Local Security Authority Subsystem Service | LSASS | Responsible for enforcing the security policy on the system. Verifies users logging on to the computer and creates security tokens. |
Winlogon | Responsible for handling the secure attention key, loading the user profile on logon, and optionally locking the computer when a screensaver is running. On Windows NT systems prior to Windows Vista, Winlogon is also responsible for loading GINA libraries which are responsible collecting logon credentials from the user. | |

System startup (Windows NT) Rencana–rencana utama: Windows NT Startup Process dan Windows Vista Startup Process | ||
NTLDR, IA64ldr, Winload | The boot loader; performs basic system initialization options such as loading the hardware abstraction layer and boot-time device drivers, prior to passing control to the Windows kernel. In versions prior to Vista, NTLDR and IA64ldr also display menus to the user if multiple operating systems are defined in boot.ini, or if F8 is pressed. | |
Recovery Console | Provides the means for administrators to perform a limited range of tasks using a command line interface, primarily to aid in recovering from situations where Windows does not boot successfully. | |
ntdetect.com | Used during the boot process to detect basic hardware components that may be required during the boot process. | |
Windows Boot Manager | In Windows Vista and later operating systems, displays boot menus to the user if multiple operating systems are configured in the system's Boot Configuration Data. | |
