I have a Windows 7 laptop, and accidentally changed the default settings for all programs.
Now all of my files and programs seem to have been changed to word documents, and they do not open. I cannot even open the internet any more in order to find a solution (I'm on a different computer at the moment). I have tried opening files using different methods, but for some reason, it seems to request that I download something. If I click 'open' it opens a webpage, which then closes before loading.
If anyone could offer me some help, and tell me how to go back to my original settings, that would be great. If possible, I would like as much detail as possible.
