Disabling the DOS 8.3 name convention in NTFS

To disable the DOS 8.3 name creation convention on an NTFS partition, you must open the registry editor, navigate to HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\ Control\FileSystem, and change the NtfsDisable8dot3NameCreation value from 0 to 1. By doing this, you may experience problems while installing certain software packages, such as Office 97. You can always re-enable it for installations to get around that problem. Note: Please remember that editing your registry can be risky, so always have a verified backup before you begin.
