Hi, I have a friend's Windows 7 machine which has started to show 80070BC9 when trying to install Windows updates. I believe this refers to a 'pending update' which needs to be completed before other updates can follow (normally after a reboot).

I am running windows 7 sp1. I have tried updating manually a few different updates, Update for Windows 7 for x64-based Systems (KB2830477) Update for Windows 7 for x64-based Systems (KB2952664) Security Update for.NET Framework 3.5.1 on Windows 7 and Windows Server 2008 R2 SP1 for x64-based Systems (KB2478662) Security Update for.NET Framework 3.5.1 on Windows 7 and Windows Server 2008 R2 SP1 for x64-based Systems (KB2446710) Cumulative Security Update for Internet Explorer 11 for Windows 7 for x64-based Systems (KB2929437) they have all failed and i have tried countless times. After i shut the computer down and boot up again, it will show 'configuring windows. ' then after a about 10 seconds, it will say that it has failed and it will shut down and restart.

After it has restarted, it will show the same configuring screen again, and the same thing will keep happening about 3-5 times, until it finally brings me to the start page.

Try to install updates again Important The following issues occur when you do this: • Updates that are currently downloaded but that have not yet been installed have to be downloaded again by using Windows Update or Microsoft Update. • When you delete the Software Distribution folder, your download history is removed. • If you currently receive updates from Microsoft Update and from Windows Update, you will have to re-select this option from the Windows Update Web site. Note: If the issue is resolved and you can successfully download and install updates, you can safely delete the SoftwareDistribution.old directory to recover disk space Note: If the issue still persists, I would recommend you to run the, The System Update Readiness Tool can help fix problems that might prevent Windows updates and service packs from installing.
