My wife's Windows 7 laptop cannot install "Update for Windows 7 for x64-based systems (KB971033)" )(labelled "important"). Her machine has attempted to install it just about every day since 3/11/2017. The failure error code is 80073712, but I have had no luck figuring out what that means.
In the past I have had some Windows Update problems that turned out to be due to malware, so I thought I'd give FRST a try. Logs are attached, I'd appreciate any help.
