Default Description
[Enabled] Allows the user to enable and disable the Execute Disable
Bit functionality. Execute Disable Bit allows the processor
to classify areas in memory where application code can

attempts to insert code in the buffer, the processor
disables code execution to prevent damage or worm
propagation.
