How to modify the startup type of the service?

Enter "services.msc" or "service" in the "Search Programs and Files" column of the Win7 Start menu to search for "Services" item, you can open the service management list window after clicking. Double-click on any service to view or modify its properties. In the Properties window, you can modify the startup type to Manual, Auto, Auto (Delayed) or Disabled.

What is the difference between "automatic" and "automatic (delayed start)"?

"Automatic" startup means that the service item is loaded at the same time as the computer starts to support other services based on this service. The program that runs on it. And "automatic (delayed start)" is a very user-friendly design in Windows 7. Starting in this way, you can delay the startup of the service item after the system is started for a period of time. It can solve the problem that some low-configuration computers are slow to start or slow to respond after startup because of too many service items.

What is the difference between "manual" and "disabled"?

When the service startup status is "manual", the process is closed but can still be activated under certain circumstances. When set to Disabled, the service will not run unless the user manually modifies the properties.

Which services need to be manually started?

"Manual" mode, as the name suggests, is that this service does not load as the system starts, but requires other services to be activated or the user enters the service management interface. After that, start it manually or modify its properties to start "automatically".

This mode is often used when you need to turn on some features that were not turned on. Take the "ApplicationIdentity" service as an example. By default, the service is in the "manual" state, that is, it is not started. However, when users need to use the AppLocker function, they must manually enable this service (modified to "automatic" state), otherwise the AppLocker function will not work.

What should I pay attention to before modifying?

Modifying the system service may cause some unexpected problems, so it is best to back up the default service status before modifying. To open the service management window, click “Operation→Export List” and select “Save as Type” as TXT text file or CSV file. It is recommended to select the latter. This file can be opened by Excel.

In addition, if the system fails to enter the system due to a modification error, you can press F8 to select the safe mode and the service startup property in the security mode.
