Error Lookup Portable

Error Lookup Portable is a tiny and open-source application that facilitates a simple interface for looking up various computer error codes to find out their meaning, including the severity and facility.

It's available in multiple languages and wrapped in a user-friendly interface that has a real-time search function, showing results as you type. Searches can be performed in either decimal or hexadecimal mode.

There is no installation involved (not even software dependencies), so you can unpack the downloaded file and fire up the tool right away to perform searches. The main window has a simple look and tidy layout, where you can type a code in the dedicated box and read information on the bottom side.

Besides typical Windows error codes, Error Lookup Portable offers support for DirectX, NTSTATUS, Internet Explorer and STOP error codes. It's compatible with both 32- and 64-bit Windows, having two separate launchers for each architecture type.

When it comes to the returned search results, you can find out the decimal or hexadecimal counterpart of the typed code, together with the severity, facility and other details, such as system and internal modules. This includes Blue Screen of Death (BSOD), Biometric API, Performance Data Helper (PDH), Platform Specific Hardware Error (PSHED), C/C++, as well as graphics and gaming (DirectX).

As far as customization is concerned, you can make the main window stay on top of other apps, change the interface language as well as disable any system or internal modules.

The utility worked smoothly on Windows 10 in our tests and had minimal impact on the computer's performance. Searches were conducted fast.

Thanks to its straightforward options, Error Lookup Portable offers a simple solution for those interested in finding out the meaning of certain error codes. However, it doesn't provide more detailed explanations for users who aren't tech-savvy.
