| Debugging Tools for Windows |
The following table lists the flags that GFlags changes, the hexadecimal value and abbreviation for each flag, and the destination (R for registry, K for kernel, I for image file) in which the flag is valid.
For a detailed description of each flag, see the Global Flag Reference.
Important Pool tagging is permanently enabled in Windows Server 2003 and later versions of Windows. On these systems, the Enable pool tagging check box on the Global Flags dialog box is dimmed, and commands to enable or disable pool tagging fail.
Note The symbolic name of each flag is provided for reference only. Because symbolic names change, they are not a reliable identifier of a global flag.
