It is very simple my friends.. may be I am late here but I know the trouble maker.
It is a program installed on your computers known as Windows 10.
All you have to do is uninstall it .. go back to Win 7 (if not Win XP) and install your games and everything will be fine.
Microsoft is absolutely aware of this issue and it does not make a difference for them because majority (more than 99%) of the users will not install another OS or downgrade to Win 7 . If it was a Windows Server issue i.e. Business Issue , then they will force their geeks to find a solution but it is not a business critical thing (money) so simply ignore it ...
