I want to turn off support for legacy applications that don’t understand long filenames in the 8.3 character standard. How can I do this in Windows 7?

This question came from our site for professional and enthusiast programmers.
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 using 16 bit programs, a performance gain can be achieved by disabling it as follows:
Click on Start -> Run -> Regedit]
Modify/Create the Value Data Type(s) and Value Name(s) as detailed below.
Setting for Value Data:
Exit Registry and Reboot
Now any application that requires 8.3 filenames is no longer supported by the operating system, or rather by the file system.
