So how many times do you see this box shows up and telling you “Windows can’t open this file” blahblah. And stupid enough it will ask you “What do you want to do ?” by default the option points to “Use the Web Service to find the correct program” which will launch the IE and doing an endless and pointless look. And the result ? It’s totally unnecessary, and useless information. To be honest, I just hate every time when I see this prompts.

  1. Where are the under the hood hacks that you can do with Windows 7? Using this program and using that program really isn't all that interesting, but that seems that's all that is being blogged about… Kinda takes away a bit of credibility from your actual site's name: Windowsy7Hacker

    Been looking for something more lately…

  2. Rather than installing an application to do that, just set the registry entry:
    HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionPoliciesExplorerNoInternetOpenWith to 1.

  3. This sounded like a good idea ,so I tried to download the Default Editor , guess what came up , –windows cannot open this file — anyway I go I hit a dead end , don’t know where to go now , and what I’m looking for . Bill

  4. How do I reset the registry with 
    HKEY_LOCAL_MACHINESOFTWAREMicrosoftWindowsCurrentVersionPoliciesExplorerNoInternetOpenWith to 1. ?
