This isnt just Dell its also INTEL and HP and Apple and Toshiba and Lenovo and and and. There is a cost to writing new drivers and systems that are over 5 years old tend to be End of Life End of interactive support. 8 came out in 2012 7 came out in 2009 vista came out in 2007 and the GX620 was released in 2006 which is why they started having the made for XP vista Capable label. If there are no released drivers for 10 then the vista or 7 or 8 or 10 drivers can be used. Since the 790/990 also has WDDM 1.0 VISTA drivers then they work from DOS to windows 7 or 8 or 10 just fine. These drivers are not built into windows.

They are INTEL AMT SOL (Serial over LAN) drivers. The 790/990 'serial port drivers' are not 'COM port drivers' that are built into the OS all the way back to MSDOS.

I'd like to give John Makster about 99% of the credit, but his answer was buried in a forum thread that was tough to find. Intel driver detection tools also won't fix this issue. This trouble occurs when you upgrade from Win 7 which is fully-supported by Dell on these machines, to the unsupported Win 8 or Win 10.Īgain, this trouble surfaced because Dell decided not to provide support Win 8 or Win 10 for these PC's. After 3 days of digging, I found the fix for the OptiPlex 790 and 990 PCI Serial Port Driver issue which shows as a yellow triangle under Device Manager.
