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
and cannot execute. In the event an internet worm
attempts to insert code in the buffer, the processor
disables code execution to prevent damage or worm
propagation.
[Disabled] Allows the user to enable or disable the Virtualization
Technology. Note that in order for this setting to take
effect, the system must be rebooted.
