Resolution in games is only showing 1920x1080, none other than this. But I was able to change it before I got updates from dell . After the installation of updates I am unable to change resolution in games, neither from documents folder.
My Laptop is Dell Inspiron 15 5578 2 in 1
i5 7200U 2.50 GHz
1TB Hard drive
Intel HD 620 graphics
Windows 10 Home
try the restore again but turn off the updates both the dell & windows.
Turn off Windows Updates in Windows 10. You can do this using the Windows Update service. Via Control Panel > Administrative Tools, you can access Services. In the Services window, scroll down to Windows Update and turn off the process.
