On all 3 PC’s, I’ve formatted the HD and reloaded Windows 7 SP1. The reloads finished normally with no errors. I then ran Windows Update which listed over 180 updates that needed to be applied. The updates were downloaded and installed without issue. Running Windows Update again, it listed 7 more updates that needed to be installed. On all 3 of the PC’s, these 7 updates fail to install with the error code 80072EFE.
The updates that will not install are two .NET framework updates, a security update, two general updates, the malicious software removal tool, and a definition update for defender.
I’ve done this same process with other Dell models in recent days without any problems. It’s seems to be something with the 390’s. I’ve updated the BIOS and all the drivers, which had no affect.
