"[i]To open this file, Windows needs to know what program created it. Windows can go online to look it up automatically, or you can manually select from a list of programs on your computer."
which is ok if i know what program created it, but any new software that i want to install, i cant as i dont know what program to associate with it. a box also appears when i boot up with some characters followed by \windows\apppatch.
Any ideas anyone? (responses should be given in a manor when talking to an idiot as i am not experienced)
