Is it a good idea to disable short filenames on Windows 7 running on a SSD drive?

By default, NTFS creates an 8.3 filename every time it creates a long filename, which adds a bit of time to the file creation process.
One can disable that using:
fsutil behavior set disable8dot3 1

16 bit apps use 8.3 filenames.
By far the most prominent 16 bit apps are Setup programs. Not a lot of them, but some.
Like any setting, I'd test all your applications just in case. But for the most part, you should be ok.
