Err Msg is a free software program for Microsoft Windows devices that you may use to loo up error codes that Windows throws.
It happens from time to time in Windows that you stumble upon a rather cryptic error code instead of a carefully worded error message that explains exactly what happened and what do to do solve the problem.
But what if you get a code like code 646 Windows Update encountered an unknown error instead? Not very helpful, is it?
Most users in this case will probably open their favorite web browser to research the error code online.
A faster solution and one that works offline as well is provided by the program Err Msg which may reveal additional information about the error code.
The portable program displays a single input field on startup. To look up the error code enter it into the program window and hit the Error Msg button. A notification will appear that might reveal additional information about the Windows error code
In the case of code 646 it is "The driver was not loaded because the system is booting into safe mode".
The description of the error message can give you clues about the problem if it is different from the error message that Windows displays. Research on the Internet might still be the best option to resolve the issue, especially if Err Msg does not provide you with a better description.
Err Msg is a small portable software program that is compatible with both 32-bit and 64-bit editions of the Microsoft Windows operating system.
