File Format Description

File used by the Microsoft Support Diagnostic Tool (also referred to as the WTP Wizard), a Windows Troubleshooting Platform (WTP) program used to locate and fix hardware and software problems in Windows; contains a .CAB file and is used specifically for diagnosing and repairing computer problems.

If you receive a DIAGCAB file from a trusted source, you can run it natively in Windows by double-clicking the file (Windows has a file association by default). Typically, a small wizard-style program is run that guides you through a series of steps that help you locate and fix problems on your computer. When the diagnosis is complete, sometimes DIAGCAB files include an option to send helpful information over the Internet to a trusted source so that they can help to diagnose and repair your computer.

WTP programs are often used by original equipment manufacturers (OEMs) and independent software vendors (ISVs) to troubleshoot problems experienced by customers. They are also used by system administrators. DIAGCAB files are sometimes posted on websites and downloaded by users. If distributed this way, the creators of the files usually digitally sign them to verify that they are from a trusted source.

NOTE: DIAGCAB files can be created with the Makecab.exe and Cabarc.exe tools. They can be digitally signed using Signtool.exe. They are run with the Microsoft Support Diagnostic Tool, which has the filename msdt.exe.
