Computer Tip: Want to speed up Windows a bit

If you are using a Windows server or no 16-bit applications then you can actually have a performance gain by disabling the 8dot3 naming. 64-bit Windows drops 16-bit support. So it is generally not a huge problem.

Warning: There still may be some installers that could be installing 32-bit applications but the installer itself uses 16-bit applications.

Warning: As usual, use the tips I mention at your own risk. Backup the registry or the node. If you see there is a problem, undo the registry fix.

For 8.3 name creation, the default for Windows Server 2008 R2 and Windows Server 2012 is off.

There are 4 options for the 8dot3 naming:

0 – NTFS creates short file names. This setting enables applications that cannot process long file names and computers that use differentcode pages to find the files.

1 – NTFS does not create short file names. Although this setting increases file performance, applications that cannot process long file names, and computers that use different code pages, might not be able to find the files.

2 – NTFS sets the 8.3 naming convention creation on a per volume basis. (Windows 7 and later only)

3 – NTFS disables 8dot3 name creation on all volumes except the system volume. (Windows Vista and later only)

This is the registry format (note the DWORD may already exist):

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Control\FileSystem]

“NtfsDisable8dot3NameCreation”=dword:00000003
