What should I do if the SVCHOST.EXE process is high? Pull out the culprit behind

When you run the Windows Task Manager, you may see several processes with the name SVCHOST.EXE running at the same time in the Processes tab. Moreover, these SVCHOST.EXE may have one or several occupied more system resources, affecting the efficiency of the computer.

SVCHOST.EXE is located in the Windows system32 system folder and its file description is "Generic Host Process for Win32 Services". When Windows starts, SVCHOST.EXE will automatically check the system service composition of the Windows registry, build a list of system services, and then load the relevant .DLL dynamic link library file into a specific running system service. Therefore, we can think of SVCHOST.EXE as a "host program for loading system services."

Because each SVCHOST.EXE process may load one or several system services until all SVCHOST.EXE has loaded all system services, we will see multiple SVCHOSTs in the Task Manager. EXE runs at the same time, which is by design. In general, Windows XP/Windows Server 2003 may have no more than six SVCHOST.EXEs running at the same time; Windows Vista/Windows Server 2008/Windows 7 will have no less than ten SVCHOST.EXEs running at the same time.

When you view the SVCHOST.EXE process in the Windows Task Manager, the "username" of the SVCHOST.EXE process should appear as SYSTEM, LOCAL SERVICE, or NETWORK SERVICE. (If you don't see the Username in Task Manager, select View - Column Settings from the menu and check the Username checkbox.) If the username of a SVCHOST.EXE process "Shows the name of the user account (such as Administrator), then this SVCHOST.EXE is probably a malicious program.
