I have 5 updates to install, a few of them I think are not needed, but I'm not sure which ones, but there's a security update from 7/9/2013 that won't go. The offenders: Security Update for Windows 7 for x64 based systems (KB2847927) Update for Windows 7 for x64 based systems - KB2719857 , KB2732059 , KB2798162 , KB2813956 The ever-so-useful windows error codes are 800B0100 and 8024200D I also had a .NET 3.5(?) update that I was able to install after a few resets of the update service using net stop wuauserv I'd really like to install the security update. It sounds important. I downloaded the CheckSur tool and it didn't say there were any problems, but after looking at the log I see that's not the case and I have a ton of issues... I've spent the past 2 hours looking around the internet and trying various solutions and I stumbled upon this thread which looks a bit more promising. I've attached the logs and I really hope you can help!
