Fix Application has been blocked from accessing graphics hardware in Windows 10

While playing heavy games (or using other graphic intensive software), users have reported an issue where they get the error:Application has been blocked from accessing graphics hardware in Windows 10. When an application (usually a game), is new and the graphic drivers are not updated enough to support it, we get the error. However, this might not be the only reason and simply updating the drivers wouldn’t help. Here is how to fix this.
