My wife is in the Philippines and we use Skype to communicate daily. I downloaded Skype before I upgraded to Windows 10 and it worked fine no problems. Once I installed Windows 10 I have to reinstall Skype each time I turn the pc on, why? Am I doing something wrong when I installed it the first time?

Please run a system file check (SFC) & DISM (if necessary) if you are on win 8 or higher
