I've actually been able to install a fair few of the updates for a clean Windows 7 install, but there is a small hardcore of updates - including Service Pack 1, which are giving me failure errors: Code 800B0100 Code 8024200D The updates I am trying to install which fail with these errors are: Security Update KB2442962 Security Update KB2619339 Update for Windows 7 KB 2345886 Windows 7 SP 1 KB976932 As per this ( Windows Update error 800B0001 ) Microsoft support article I have run the Windows System Update Readiness Tool. The first time I downloaded the Tool using Windows Update and it found a bunch of errors (over 80) some of which it fixed (see attached logs). I then downloaded the manual version of the tool to run it multiple times. Since then there seem to be a hardcore of 16 errors it cannot fix (again see logs attached). Again, as per the above article I then tried the automatic troubleshooter (windowsupdate.diagcab). This said it found some errors as follows: Potential Windows Update Database error detected 0x80070002 Windows Update components must be repaired Security files are not registered It said all three of these errors were fixed but still the same problem is occuring. I then ran SFC /scannow as an administrator. This said it had found some problems - some of which it was not able to fix. Again I guess the log is attached below. Your help would be greatly appreciated, Many thanks. PS - I have attached my CBS folder in 2 parts due to the size restriction of the forum.
