Totally agree with this. You may install StartIsBack or Classic Shell all you want, but you'll not be able to use the neat network manager from Windows 7. It's so annoying when you have to enter passwords for VPNs, for example. You can't even click outside the password prompt, as this whole Metro thing slides back and resets your input. I asked authors of both StartIsBack and Classic Shell to figure something out, but they said they wouldn't be doing that For the Open With dialog, you can partially fix it with a tool called OpenWith Enhanced, but it has its own problems on Windows 8.1. It fails to register file associations sometimes.
