Accidentally deleted my .exe program and some others via a bunk registry cleaner, and windows cannot open any .exe files, it states needs to know what program created it, and the two options are go online to automatically look for the program-which I cannot get online with that puter as dialup dead now too, and other option is choose from a list of programs which the program that I need is not there? To Summarize problem, I used a Registry cleaner and deleted a few things I assumed were junk, but were not. I cannot access my backup files, system restore, or get online to remedy problem. If I could just open an .exe file I could go online and access Microsoft update to find what I've removed...I think that's right? Any other suggestions to open an .exe file? Can't get my Win/XP CD to boot up at startup either.
