I just thought I'd post an update here. I did change the time for the maintenance to 7:00 a.m. I get up around 6:45 a.m. and always start the computer and then it sits for an hour and a half while I program my PVR for the day and watch my morning news show while having breakfast.

Nothing changed for about two weeks and I had to update WD manually every day. Then all of a sudden about five days ago WD updated automatically three days in a row. One of those times it came through Windows Update but the other two times WD updated itself after Windows Update had run and not detected any updates. Then the fourth day I had to update it manually again, then today WD updated itself but not through Windows Updates. So there's no rhyme or reason or consistency to it. I suspect something that starts up perhaps at different times each day is interfering and have tried to figure out what by comparing the Log Collector Event Viewer update but can't find the culprit. It's not a big enough problem to spend a lot more time trying to figure out. So I just check every day to be sure WD is up to date and if not do it manually. :)

I do not think anything is wrong, as I mentioned earlier in the thread
Windows update will only offer a Defender update every so often, when an update of particular note is issued
whereas Defender update will always update if there is one available
I should add that Defender will also update -before a scheduled scan - which may well account for
. One of those times it came through Windows Update but the other two times WD updated itself after Windows Update had run and not detected any updates.

OK I understand but that's not always happening either. MS updates Windows Defender several times a day so there are always updates available in the morning when I first log on. According to the event logs, WD always does its scan without fault but only once in a while it does show that WD was updated before the scan started but not every time. It's just not typical behaviour like it was before. I never had more than one day go by without an update for WD and they always came through Windows Updates every morning. I would go to the Control Panel, see the update there and click to install it (it was always already downloaded and waiting because that's the option I had chosen). :)

Well
I do not really know what to suggest other than the obvious - as you say
So I just check every day to be sure WD is up to date and if not do it manually
The reason I say - I do not really know is because, you are not keen on a repair install of W indows, neither are you keen on trying without classic shell - (in case as you say it will not then reinstall - but of course it is no longer supported and has been replaced with Open Shell)

The only trial option that comes to mind is a test clean boot and see if then updates - just in case you are correct on the
I suspect something that starts up perhaps at different times each day is interfering and have tried to figure out what by comparing the Log Collector Event Viewer update but can't find the culprit.
presuming that it is not another Microsoft process.
Have you had a look at autoruns
to see if you can find anything

Karen, how do you update the WD manually? What exactly you are doing?

No but I might give that a try. I know MS Edge updates itself every day and I'm wondering if that's the problem because I haven't had it installed that long although it was months before this issue arose.

Yes Malcolm's right from within the WD Interface mainly because I'm already there checking to see if it's up to date.. However, I have on at least two occasions downloaded from the MS site in the hopes that might fix the issue but it didn't. :)

Karen,

I don't think that something at start-up interferes with WD. Since there are times it gets automatically its updates, it does its job. I would say, just leave it alone, at least for a while, and check. What happens if you don't update it manually?

However, take a look at this article. Perhaps it has something useful for you to try: How to change the Windows Defender update frequency (winaero.com)

After four or five days I get a message from the Security Center saying WD is not up to date and I need to take some action.
