Defrag Tools #190 - Performance Power Slider
Description
In this episode of Defrag Tools, we talk about HRESULT based Error Codes. The 32bits in the HRESULT have meanings, allowing the reader to gain additional insights into the error.
Of note:
The 32nd bit (the top bit) indicates if an error occurred or not. This is why errors are 0x8xxxxxxx.
The 16-26 bits are the Facility - the originating API (Win32, CLR, XAML, etc.).
The 0-15 bits are the (Error) Code.

Erick I love your show, and that you keep it all available, thank you.
Could you all explain how to download symbols to an offline machine. Microsoft has made them so they cant be downloaded. I want to troubleshhot a computer offline because of datalogging troubles. I wonder if there is any way to download and use them.
The insider show is good stuff too, thanks.
