Default Behavior

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


While Browser is stopped, the Workstation service cannot be launched.

Restore Default Startup Configuration of Browser

1. Run the Command Prompt as an administrator.

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

sc config bowser start= demand

3. Close the command window and restart the computer.

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