Count me in. My MicrosoftUpdate log shows 4 , count them 4 successful
applications of the definition update. However, only the last one, via
manually run Microsoft Update--worked as far as the Windows Defender UI is
concerned. I didn't do any of the futzing around with KB articles, or
repairs or uninstall/reinstalls--just went to MicrosoftUpdate after what I
thought were two attempts to install from within the program. Turns out
that AutoUpdate had made a previous try.
