Use description

Multiple svchost.exe processes can exist at the same time. In Windows 2000, there are generally 2 svchost processes. One is the RPCSS (Remote Procedure Call) service process, and the other is svchost.exe shared by many services. In Windows XP, there are generally more than 4 svchost.exe service processes, and in later systems there are more (usually 6 in Windows 7, but the number is not absolute in all systems, sometimes more or less This is a normal phenomenon at all, and whether it is a virus or not cannot be unfounded, and needs to be judged using reasonable methods). This reduces the consumption of system resources to a certain extent, but it also brings certain instability factors, because any service in the shared process exits the process due to an error, which will cause all services in the entire process to exit.

In recent years, due to the general improvement in computer performance, in order to improve system security and stability, in the latest version of the Windows 10 operating system, the system no longer allows multiple services to share one svchost.exe process, but An independent svchost.exe process will be assigned to each service. Therefore, after updating to the latest version of Windows 10, you can see 80 to 90 svchost.exe processes in the Task Manager, which is normal.

In addition, in 64-bit Windows systems, there is also a svchost.exe file in the SysWOW64 folder under the system disk (located in the Windows folder), which is the 32-bit version of svchost.exe. Run a 32-bit service on a 64-bit Windows system. In 64-bit Windows operating systems, most system files located in the System32 folder have a corresponding 32-bit version in the SysWOW64 folder, so there is no need to worry.
