The default services list is available in the NT 4.0 help files. The driver list comes from Microsoft’s MSDN online library. Beware of disabling services that depend on other services, as noted below. Remember to be careful when you work with devices and services. For your reference, here are a couple of tables giving the names and purposes of the drivers that ship with Windows NT (Table 1) and the default services used by the OS (Table 2). For example, Sparrow.sys is the name of the Adaptec SCSI driver. One thing that interferes with troubleshooting Windows NT is the vague naming convention for many devices and services. But which drivers drive which hardware, and what do those services do? As for services, sometimes you don’t need them, and you can save system overhead by turning them off. Unlike Windows 98, it’s very hard to remove them when you need to (for example, when you change hardware and drivers) and often wiser just to put them on the disabled list. In Windows NT, tons of devices (device drivers for hardware) and services (useful software for the operating system) are registered in the OS, whether you ever use them or not. Some start at boot, some are automatic, and some are manual. If you’ve ever browsed through your Devices and Services applets in Control Panel, you’ve seen a lot of entries. Here, for your reference, is a list of default drivers and services. Windows NT 4.0 default drivers and servicesĪmong the problems troubleshooting hardware in Windows NT is the fact that drivers and services use vague names.
