I was opening a zipped putty file sent by a colleague who suggested to me to use
Notepad to open after unzipping.
I don't know what I've clicked or selected: now every single executables (MS outlook,
Chrome, IE, Google Docs, 7zip, putty, Broadband on Mobile, etc) are showing Notepad
icons & when I double-click on them, Notepad edits those executables & show their
contents (often containing garbage characters).
What can I do to "de-associate" the Notepad associations?
I'm on Win 7 Professional x64
