A system error code is an error number, sometimes followed by a short error message, that a program in Windows may display in response to a particular issue it's having.
System error codes are provided to software programmers as part of the programming interface with the Windows operating system. In other words, system error codes are predefined error codes and error messages that software programmers can use with their software to tell you (the software user) that the program is experiencing a particular problem.
Not every software program uses these predefined system error codes. Some software programs have their own sets of error numbers and error messages.

Important: A system error code is not the same as a Device Manager error code, a STOP code, a POST code, or an HTTP status code (a.k.a a browser error code or an Internet error code).
Some system error codes share code numbers with these other error code types but they are completely different errors with different messages and meanings.
Also Known As: error code, operating system error code
Examples: "I received an Error Code 206 when I was trying to save a file in a music editing program. After looking it up, I found out that it meant that the file name I was trying to save my music file as was too long. 400 characters probably was a bit long."
