I'm not sure what happened, but ALL exe files on my computer no longer work. However, Python stuff still works. Something edited the registry and changed the values for .com files, .exe files, and more. If I changed them back through a Python program, would it would they start to work again?
Update: Nvm, I found a site (http://www.dougknox.com/xp/file_assoc.htm) and it has .reg files that fix all types of fiels for windows.
