Microsoft Error Lookup Tool

The Microsoft Error Lookup Tool displays the message text that is associated with a hexadecimal status code (or other code). This text is defined in various Microsoft source-code header files, such as Winerror.h, Setupapi.h, and so on.

System Error Codes are very broad: each one can occur in one of many hundreds of locations in the system. Consequently, the descriptions of these codes cannot be very specific. Use of these codes requires some amount of investigation and analysis. You need to note both the programmatic and the runtime context in which these errors occur.

Because these codes are defined in WinError.h for anyone to use, sometimes the codes are returned by non-system software. And sometimes the code is returned by a function deep in the stack and far removed from code that is handling the error.

The following topics provide lists of system error codes. These values are defined in the WinError.h header file.

• System Error Codes (0-499) (0x0-0x1f3)
