Default Behavior

Windows Installer is a Win32 service. In Windows 10 it is starting only if the user, an application or another service starts it. When the Windows Installer service is started, it is running as LocalSystem in its own process of msiexec.exe. If Windows Installer fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the msiserver service has failed to start due to the error.

Dependencies

Windows Installer cannot be started under any conditions, if the Remote Procedure Call (RPC) service is disabled.

Restore Default Startup Configuration of Windows Installer

Before you begin doing this, make sure that all the services on which Windows Installer depends are configured by default and function properly. See the list of dependencies above.

1. Run the Command Prompt as an administrator.

2. Copy the command below, paste it into the command window and press ENTER:

sc config msiserver start= demand

3. Close the command window and restart the computer.

The msiserver service is using the msiexec.exe file that is located in the C:\Windows\system32 directory. If the file is removed or corrupted, read this article to restore its original version from Windows 10 installation media.
