Windows XP Console Commands-auxiliary operations and special function commands

Editor's note:
Windows XP (including Windows 2000) console commands are a very effective tool for diagnosing and testing and restoring system functions in some unexpected situations. Xiaobian has always wanted to make a summary of the commands in this regard. This hard-working old fan sorted out this practical secret.

CLS

Clear the screen.

Only the command prompt and insertion point are displayed on the cleared screen.

Disable

Disable Windows XP, Windows 2000, or Windows NT 4.0 system services or device drivers. The disable command is only available when you use the fault recovery console.

Disable {SERVICE_NAME] | [device_driver_name}

Parameters

SERVICE_NAME

The name of the System Service to be disabled.

Device_driver_name

The name of the device driver to disable.

Example

In the following example, the EventLog Service is Disabled:

Disable EventLog

Note:

The disable command sets the Startup Type of the specified service or driver to service_disabled.
When you disable a system service or device driver by using the disable command, the name of the last Startup Type of the system service or device driver will be displayed on the screen. You should write down the name so that you can use the enable command to restore the Startup type to the previous setting as needed.
There are five startup types. The first three types are service_auto_start, service_disabled, and service_demand_start. The corresponding standard start type: automatic, disabled, and manual, usually configured using the "service" in the "Computer Management" management tool. The last two types are service_boot_start and service_system_start, which are usually used to configure the method for loading the device driver. For example, load a file when the computer is started or when Windows is started.
Enable

Enable Windows XP, Windows 2000, or Windows NT 4.0 system services or device drivers. The enable command is only available when the fault recovery console is used.

Enable {SERVICE_NAME | device_driver_name} [startup_type]

Parameters

SERVICE_NAME

Name of the System Service to be enabled.

Device_driver_name

The name of the device driver to be enabled.

Startup_type

The Startup type to assign to the service or device driver. Valid start types include:

Service_boot_start
Service_system_start
Service_auto_start
Service_demand_start
Example

In the following example, set the start type of the EventLog service to automatic or service_auto_start:

Enable EventLog service_auto_start

Note:

If no Startup type is specified, the enable command lists the current startup types of the service or device driver specified in SERVICE_NAME.
When you use the enable command to change the Startup type, the name of the last Startup type is displayed on the screen. You should write down the name to restore the Startup type to the previous setting as needed.
