I have attempted to fix .exe problems that started a few days ago on my Windows 7 HP laptop. First Steam, then AMD display programs, video players, then more programs. No viruses or malware found. I tried a fix using regedit (https://support.microsoft.com/en-us/kb/2688326) but the registry is now completely broken and will not start any third party .exe, including startup programs, other than Foxfire and some web plug-ins it seems (ex: Youtube works).
I cannot access regedit, cmd, or other Windows utilities either, just Windows Explorer. I thought I could find a clean default registry file/s to install to fix the issue that I have only made worse but I only find more advise using utilities I can no longer access.
Short of reinstalling Windows, is there a solution. Thanks for any help.
