Default Behavior

AppvStrm is a file system driver. In Windows 10 it is starting only if the user, an application or another service starts it. If AppvStrm fails to start, the failure details are being recorded into Event Log. Then Windows 10 will start up and notify the user that the AppvStrm service has failed to start due to the error.

Dependencies

AppvStrm cannot be started under any conditions, if the FltMgr service is disabled.

While AppvStrm is stopped, the Microsoft App-V Client service cannot be launched.

Restore Default Startup Configuration for AppvStrm

1. Select your Windows 10 edition, and then click Download.

2. Save the Win10_AppvStrm_Service_Startup.cmd file to a local storage device.

3. Run the saved file as an administrator.

4. Restart the computer.

The AppvStrm service is using the AppvStrm.sys file that is located in the %WinDir%\system32\drivers folder. If the file is changed, damaged or deleted, you can restore its original version from Windows 10 installation media.
