MSS: (NtfsDisable8dot3NameCreation) Configure 8.3 short name creation for NTFS

Download ADMX

Controls whether NTFS generates short file names in the 8.3 format (e.g., "PROGRA~1") for compatibility with older 16-bit applications. Disabling 8.3 name creation can improve directory enumeration performance and is recommended unless legacy application compatibility is required.
