Wow, You are absolutely right!
This PC was built to replace my own by the college where I was working part time because mine got damaged during the evening IT classes I taught for retired folks.
Both Vista and Office 2007 were installed under their volume licence and I was permitted to keep the OS and Office when the courses ended.
That is why the OS is in such a poor state, I have had no way to Refresh or repair the install!
It now takes fully 25 minutes from Boot to a Working desktop; an AV Scan paralyses the poor thing completely for around 90 minutes every week!
Why do I still use it?
Because we're both getting on a bit and I pretend that we understand each other!
...Besides, I've not yet fully taken to Win 10, despite having had my Erazer Laptop over 18 months, and having built myself a little Win 10 Pro NUC a few months back.
I don't suppose I'll ever completely retire my Vista machine, because I occasionally need Office but can't justify the cost of installing it on my newer machines.
Regards Office updates, never really noticed if they are also delivered via other routes, but I have certainly always noticed them listed in my monthly updates lists, ...back when they were automatically delivered without all this pfaff!
So, does this mean that all is as it should be this month?
Does this just mean that for December, Dalai will publish the initial update that needs downloading prior to sending "wuaserv" off to find the month's list?
...or is something different afoot?
This "solution" is only a temporary workaround and a new Win32K.sys update(s) will be posted on Dalai's webpage on 13-Dec-2016 that will have to be pre-installed before you run Windows Update to install your December 2016 Patch Tuesday updates.
Thanks again for your excellent help, if only Mocrosoft were as helpful!
