So I was fixing something with Regedit and I know I typed something in by mistake because now my system won't open any .exe program. That includes regedit so I don't know how to fix it. Help, Please?
I have Windows 7.
Depends on exactly what you have done but the most likely cause is that you've damaged the registry entries which tell windows how to handle files with the exe extension. Unzip the attached and run it on the problem pc to restore your registry settings for exe files. It is a .reg file, not an exe file so you shouldn't have that problem running it.
