mikemuch writes "The new TweakVista utility from Stardock surfaces some of Vista's more obscure settings, giving access to diagnostics and making suggestions for services that you should be running. ExtremeTech's review of TweakVista generally likes the software, and though it's called version 0.9, it is for sale — $19.95 — and feels feature-complete. More suggestions on system optimization, however, would be helpful. From the review: 'According to TweakVista, on July 1st, the "Windows Shell Services DLL service took 651ms longer to shut down than usual." That's nice. Other than this stark presentation, there's no digestible information as to why the shell services DLL took over half a second longer to shut down. And there's no hint as to what to do about it.'"
