Windows: Remove the "Use web to find program to open Unknown File Type"

HKEY_LOCAL_MACHINE \ SOFTWARE \ Microsoft \ Windows \ CurrentVersion \ Policies \ Explorer

Now in the right pane of the window create a 32-bit DWORD value:

• Name: NoInternetOpenWith
• Value: 1

RunAs tweak

If you selected "Select a program from a list of installed programs", you would get this much more useful dialog instead:

The registry hack will show you the second Open With dialog instead of that irritating first one.

Manual Registry Hack

Open regedit.exe through the start menu search or run box, and then browse down to the following key (create the key if it doesn't exist)

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\

Windows\CurrentVersion\Policies\Explorer

Create a new 32-bit DWORD value on the right-hand side with the following values:

• Name: NoInternetOpenWith
• Value: 1

The change should be immediate, no need to restart anything. To reset back to default, set the value to 0 or delete the key.
