How do I delete a useless service in Windows?

The Windows service, also known as Windows Services, is the foundation of the Windows operating system and the Windows network and is part of the core of the system and supports various operations across Windows. Services such as DNS clients, print programs, Windows Update Services, scheduled tasks, Windows Time services, alarms, and so on, are related to whether the machine works correctly. Failure to properly manage these services can affect the normal operation of the machine.

First, what is Windows services

The Windows service, also known as Windows Services, is the foundation of the Windows operating system and the Windows network and is part of the core of the system and supports various operations across Windows. Services such as DNS clients, print programs, Windows Update Services, scheduled tasks, Windows Time services, alarms, and so on, are related to whether the machine works correctly. Failure to properly manage these services can affect the normal operation of the machine.

A service is first a Win32 executable, or it is rundll32.exe to run one. DLL in a way that forms the process.

Unlike a normal application, such as opening Word, there is an interface out, but the service does not have a user interface. It cannot be run directly by double-clicking the corresponding. EXE program to run. And how does Windows control a service?

Windows services are managed by a higher level of services.exe, which is managed by the service, which is responsible for starting, stopping, running, pausing, and so on. Our most common operation is to do this through the Windows Service MMC interface.

Second, how to remove Windows services

Now the rogue software, more and more to register themselves as a service. In the HijackThis scan log, the non-Windows system services are generally listed in 023 ways, as in the following paragraph:

O23-unknown-Service:bkmarks [provides the data protection mechanism of the transmission protocol, which effectively maintains the security and integrity of the data transmission. ]-C:\WINDOWS\SYSTEM32\RUNDLL. Exe

O23-unknown-Service:ewido Anti-spyware 4.0 guard [Ewido Anti-spyware 4.0 guard]-D:\Program files\ewido anti-spyware 4.0\ Guard.exe

O23-unknown-Service:ksd2service [Ksd2service]-C:\WINDOWS\system32\SVCH0ST.exe

For these rogue software, you need to delete the relevant. EXE file, so that it can no longer run, or directly clear the service itself, so that the computer restarts, it will not start again.

There are two ways to delete:

method One: use sc.exe this Windows command

Start-run--cmd.exe and enter SC to see it. The way to use it is simple:

SC Delete "service name" (if there is a space in the middle of the service name, it needs to be quoted before and after)

As for the above: SC Delete Ksd2service (this method I have tried to do)

method Two: Direct registry Editing (not recommended)

Open Registry Editor and locate the following key value:

HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services General Service will show a key in the same name here, directly delete the relevant keys can be.

Iii. Special Circumstances

1, if the service display is rundll32.exe, and this file is located in the System32 directory, then you can not delete this rundll32.exe file, it is the Windows system files. Then just clear the relevant services.

2, if a service deleted immediately and automatically established, indicating that there is a process in the background monitoring, protection. You need to kill the corresponding process in the Process Manager first, or press F8 after startup to remove it in safe mode.
