Example 3: Setting a Flag by Using Its Hexadecimal Value

The following command sets the system-wide Enable page heap flag. Enable Page Heap adds a guard page and other tracking features to each heap allocation.

The command uses the /r parameter to indicate system-wide registry mode. To identify the flag, the command uses 2000000, which represents 0x2000000, the hexadecimal value for Enable page heap.

Although the command sets a flag, it omits the plus (+) sign. When using hexadecimal values, the sign is optional and add (+) is the default.

gflags /r 2000000 

In response, GFlags displays the system-wide flags set in the registry. The display indicates that the command is successful. The Enable page heap feature will be enabled for all processes when Windows restarts.
