Well it's been a good run, but it appears we have reached the end of the line for any further Microsoft Windows 10 support for our S7-392 laptops.
Older versions of Win10 still work, but the newest release of Win10 (version 1809) cannot be installed because Microsoft has mandated new requirements for Windows DCH compliant graphics display drivers. This new Windows DCH compliant driver is required for any new releases through Windows Update. Intel has already announced that they will not develop new Windows DCH compliant drivers for their older products like the Intel HD4000 Graphics Adapter which is what Acer built into our Acer S7-392 laptops.
I have enjoyed the S7-392 for years, and I haven't upgraded because it has worked like a champ for over five years, and still looks beautiful too. But I guess I have no option if I want to keep up with the latest versions of Windows. Time to look for something new.
