Steps to decode Windows Error code


In Microsoft world, many times we come across these types of errors (Message box with some error code / Hex code). I have experienced this on Windows services / Visual studio / Task schedulers / office tools etc.

A quick tip to analyze these errors or at least understand the cause before we hit Google and look for solution.

Using These Steps

  1. Sample Error

  3. Click on the ‘Hex’ to convert it to Hex value. Value you should get is – ‘80070775’.
    // 8007 - Represents Win 32 Status code.
    // 0775 - Represents the error code.
  4. Enter the Error code – 0775 in the calculator, make sure ‘Hex’ is selected.

First, nothing against your post.

Error decoding is a subject as old as Windows programming, and by just googling a bit you can find gems like this: Making Sense of HRESULTS | Fabulous Adventures In Coding[^]

A long time ago (nearly speaking in tenth of years) I was using a tool named HR Plus. If you search for some time, you'll surely find it; else I can provide an old copy.

Anyway, this is nice that you posted something and tried to help the community.
