Cumulate Update (KB3172985) Windows 10 version 1511 build 10586.494

Mine went to 72 percent quickly and hung up. I hit the power and selected restart. It updated all but the cumulative and once it restarted selected settings and update and it downloaded the rest very quickly and upgraded flawlessly.

This morning I notice cpu usage is high and Windows modular installer worker service is consuming cycles. All my updates installed ok the other night and since then several successful reboots. It's seems related to the update service though. So I check for updates manually and it's stuck on checking for updates. Annoying. So I then decide to reboot and despite no apparent updates bring found and/or installed my machine is on blue screen sticking on 'preparing to configure updates' yet doing nothing - any advice?

I had the same thing this morning on one of my desktops (10 Pro x64) and after 30 minutes of it I shut it down by turning off the power then rebooted with no problems then deleted everything inside the Download folder in "C:\Windows\SoftwareDistribution\Download" and upon a restart everything was fine and no more "preparing to configure updates"

Update - I left it about twenty mins and nothing changed. The only way I could turn it off was to do something I hate doing, hold down the power button until the computer shut off. I then restarted fearing the worst but it all booted up fine without drama. All seems back to normal, checked manually for Windows updates which it did and reported back within a few seconds system is up to date.

But this glitch has concerned me. Is the anniversary update out today on one of the inside rings? Might there be some background noise which meant something caused this to happen on my machine? Although I am not on any inside ring whatsoever could MS be pre downloading stuff relating. I'm a little worried that (a) this could happen again if I give the PC enough idle time (that's what happened earlier, initially all was good and went away and left the machine alone for ten mins whereupon I come back to find the modular worker service started) and (b) it now concerns me this drama will scupper the anniversary update/download on 2nd Aug when it happens

Ok thank you, interesting that it's not isolated case. I just posted again and did much the same as you although I didn't delete all the stuff in the download folder.

i do wonder if it's related in some way to the anniversary update. The whole drama spooked me - definetely not the sort of panic I needed just before heading out to work, I only turned it on to check a few emails!

Kind of difficult to decipher what MS is doing with all the changes and even though on the whole I don't get problems sometimes things do crop up that kind of makes one skip a heartbeat hoping it won't turn to a major drama which require to have an earlier image installed

Yep mine skipped a beat too. Windows 10 is certainly an unpredictable beast. I do have an image from a couple months back but don't really want to be messing with that. Not enough spare time to deal with things it throws up & restoring the work done since. Oh well, maybe it's just a temporary glitch in the matrix. This evening I'll switch it on and allow the PC some idle time to see if it crops up again, if it doesn't happen again I'll just try and put it to the back of mind. At least until Aug 2 and anniversary update day when I will hold my breath and cross every finger in the hope it goes in without drama.

i miss the days of the early computers such as my Commodore 64 and Amiga. Much simpler back then, no updates to worry about, no unpredictable behaviour!!!
