I had Windows 7 now it's Windows 10. I install many add-ons for my Microsoft Flight Simulator. I will explain my procedure, let me know if it's ok. I click on properties > Compatability, I then choose Windows 7 in the drop down. I have my UAC all the way down, yet I still tick the Administrator Rights box. Under Security, I add then type in 'Everyone ' in the box. Is there a better way or something I don't have to do? Thanks
