This application is originally needed for internal Windows purposes. Microsoft itself does not disclose all the information about this application and it is quite difficult to understand its purpose. However, it is easy to notice that the process is not used very often. It runs in the background when the operating system needs to perform certain internal actions, and then disappears again.
Many users complain that the process winrmsrv.exe requires firewall access for some reason. The original version of this process does not require firewall access to the network. It performs tasks using what is still on your system, so there is no need to connect to the network. A suspicious process called winrmsrv.exe that requires network access is definitely a virus. In most cases, this name is used by Trojans as a disguise.
