Enable/Disable command prompt extension (Win XP)

NTFS file system in XP maintains liast access/update details for each file and directory. This information is useful sometimes but for an average user this may not be of much use most of the times. Doing this takes considerable resources and as such it may make sense to diable it. Even after disabling it you still have access to last modified info which would still be available. To disable lass access update feature, do as follows:

Navigate to [HKEY_CURRENT_USER\Software\Microsoft\Command Processor] and look for the data key "EnableExtensions" and set its value to 1 to enable command prompt extension or 0 to disable this feature.
You can enable/disable the extensions for the command shell you are in by issuing the following commands:
cmd /y disables command extensions for this cmd session
cmd /x enables command extensions for this cmd session
