One of my favorite new blogs is Hacking Windows 7 Media Center, where proprietor Michael Healy has been serving up a steady diet of tasty tweaks for Media Center fans like me who are testing the feature in Windows 7.
But I have to disagree, vigorously, with yesterday’s post explaining how to change the default blue theme to an edgy black (the original instructions were posted to the Australian Media Center Community site). Yes, the new look is sleek and very cool. See for yourself:
What’s the problem? Well, in order to make this change, you have to change permissions on areplace a crucial DLL file, ehres.dll. And that means downloading a hacked file from an unknown, untrusted source.
That’s problematic for two reasons: First, you have no idea what changes were made to the contents of that DLL. I doubt that it contains any hostile code, but do you want to find out the hard way? Second, and more important, this trick defeats the whole point of beta testing, which is to discover bugs and incompatibilities in code that is still under development. If you start tampering with system files, you add another variable and render any bug reports suspect.
By the way, the same caveats hold true for the instructions over at MissingRemote on how to enable concurrent Remote Desktop sessions in Windows 7. In that case, the hack involves replacing the DLL that handles Terminal Server duties with one that’s been hacked to remove the one-session limitation. I won’t be installing it here.
