I run a 6-month old PC with 64-bit Win 7 OS. After Windows update had finished its latest round of updates today and presented me with the update log, I noticed that there are five failed important definition updates for Windows Defender KB15597. These are: 1.79.308.0 1.79.1432.0 1.79.1818.0 1.81.1347.0 1.81.1622.0
However, definition 1.81.1890.0 (the latest) was successfully installed on 17th May.
In the case of KB15597 does the latest update write over the previous / earlier updates, or are they all cumulative? (i.e. Do I need to try and obtain / install these failed updates again, or can I ignore them since later ones have installed OK?
Thanks for the reply northumbria61. Since I have never downloaded updates manually on this PC, but have always relied on Windows automatic mode, surely in this mode the updates would not download a second time if they were present & correct.
So, how do I check that these versions of KB15597 are present & working correctly?
Thanks for the link to the Belarc scanner onthelimit. I have downloaded and installed this. It's a great tool. It provides more info about your system and installed software than any other analysis tool I've seen - well worth having on any PC - so many thanks for that! It also shows that the latest Windows Defender updates have installed OK, so I'm 'in the clear'.
Thanks for your responses northumbria61. Yes, it is my entry on the Microsoft Answers forum. I have now updated that. The version of Windows Defender I am running should be the latest as the PC was new in December. The version in your link was published in May 2007 - well before this PC was built.
I realize the link I gave you was OLD - I just couldn't understand why most of the links about Windows Defender KB15597 referred to a BETA version which is why I queried whether you were running an older version. I agree with you BELARC is a great tool.
