How do I go in and change it back to default of opening with the correct program I was trying to bring up files from and old hardrive and accidentally set notepad as my default program to open everything how do I fix it.
okay, this is going to sound silly but f*** what these other guys try to sell you. download a program you don't really need like itunes
(as long as it shows up when you right click a file and 'open with - default programs - other programs')
once all the files are trying to open in itunes delete itunes
(with itunes i had to go to add/remove programs in control panel)
all files should still have the itunes icon after deletion of itunes. now restart your computer. works like a charm. they will all be back to default files. spread the word.
