Disable 8.3 Name Creation in NTFS

Files that use the 8.3 naming convention can degrade NTFS drive performance.

Unless you have a good reason for keeping the 8.3 naming convention intact (such as if you’re using 16-bit programs), a performance gain can be achieved by disabling it.

Set the Registry

DWORD key HKEY_LOCAL_MACHINESYSTEMCurrentControlSetControlFileSystemNtfsDisable8dot3NameCreation to 1.

Exit the Registry and reboot.
