Hi, I'm having an issue with Windows 7 home premium 64 bit, I updated my pc and when i logged in i noticed non of my usual startup programs ran (Steam, Skype even my PIA VPN client wont launch. I've tried rolling back the updates and even tried to use a system restore from a month before i updated and it didn't work i still cant launch any .exe programs tried all the file association issues that people have recommended in registry. Please help last hope before i do a clean install. Thanks
