Additional Technical Info The first byte defines which drive types to EXCLUDE from Autorun behavior. The hex value of the byte is the sum of all of the drive type values to exclude + 128. DRIVE_UNKNOWN 1 DRIVE_NO_ROOT_DIR 2 DRIVE_REMOVABLE 4 (floppy disks and removable cartridges) DRIVE_FIXED 8 (hard disks) DRIVE_REMOTE 16 (network drives) DRIVE_CDROM 32 (CD-ROMs) DRIVE_RAMDISK 64 The default configuration excludes UNKNOWN (1), REMOVABLE (4) and REMOTE (16) which would be 16 + 4 + 1 + 128 = 149, which is hex 95. If you take out REMOVABLE you get 16 + 1 + 128 = 145, which is hex 91. The calculation for this value is 1 + 4 + 16 + 128 = 149. 149 Decimal is 95 Hex The new calculation is 1 + 16 + 128 = 145. 149 Decimal is 91 HexYou may have to restart for the system to recognize a floppy or Zip as an Autoplay drive.
