    Oh - you think it keeps restarting the download...

    Would there be anything in Update History in that case, to confirm that?

    Fortunately, at home the connection isn't metered. Only when I'm traveling and using a MiFi on Verizon......

    I suspect y'all were right about what was happening 'cause yesterday afternoon, not too long after posting all that stuff, the laptop had some kind of seizure and decided it just ABSOLUTELY, RIGHT NOW, had to install the Creators update AGAIN..... I have no idea why, or what it was thinking, but I told it to go ahead, the thing sat and churned for a couple hours, downloading and doing whatever, and finally belched, rubbed it's tummy, and rebooted......

    As NEAR AS I CAN TELL, the dozens of edb.log (sp?) files are gone, and after a couple disk cleanups, the remnants of windows update and postvista?? are gone, AND it appears NOT to be constantly churning...

    To my non-expert eye, there still seems to be a lot of reading and writing going on, even though the laptop is just sitting there with nothing obvious and actively running except the task manager and resource monitor, but mayhap that's just what laptops do. The desktop doesn't seem to have nearly as much disk activity going on when it's sitting quietly, but at least the cpu isn't 15-18% busy and the disk isn't 50-60% busy continuously...

    Previous Creators update failed? Almost failed? I did something stupid? Cosmic Rays? Poltergeist?

    Anyhow, thanks, another crisis resolved (hopefully)!

    Hi, so it seems what you were seeing was the consequence of travelling....? So... a workaround would be not to travel or not to take it with you and use it without an unlimited connection...

    Ok, good.. though I'm not impressed with what you've seen from a design point of view. (I have Win 10 Pro, and have feature updates deferred = I'm not getting the CU for a while).

    Also I have updates set to notify only (Winaero's free tweaker - with full explanations) and that should also prevent such behaviour (hint).

    Laptops? Here's mine when idle. I'd like to understand why that top process uses CPU time. I've not really investigated - only tried a couple of simple things.

    Background resource usage when idle should depend on what start-ups you have, ideally.

    Cosmic Rays - I posted an article I found in the VIP lounge some weeks back... not seen a thread on poltergeists- yet- or maybe it's been moved.

    Well, I'm glad to see that you aren't rejecting the whole cosmic rays or poltergeist theories out of hand!!!!!!!!

    I like traveling, so I'm not gonna quit doing that - of course my method of traveling involves taking along a kitchen, bathroom, comfy place to work with a big screen tv, and so on...

    I've got the laptop set up so IN THEORY it doesn't try to do stupid things like downloading updates when it's on the metered connection. Not sure what happened this time, but at least it's stopped beating it's brains out...

    I"ll have to take a look at the Winaero's free tweaker to see if it'll help keep me out of trouble!

    Sounds good.. especially the home comforts! Setting to notify only is a real boon in that it also means no risk of unexpected restarts.
    Nothing magic about Winaero's tweaker- it's just a convenient way to do things available by the Group Policy editor (Pro upwards) or in the registry.

    The Creator's Update extends Active Hours from 12 to 18 to try to restrict that possibility, but will deliver 'critical' updates even on metered connections. Other changes related to controlling updates apply too.

    As and when you face that, best practice (which regular contributors here use routinely) is to create or update your disk image (e.g. Macrium Reflect (free) + its boot disk + large external medium for image storage.

    Disk images let you restore your PC to a previous working state when things go badly wrong, relatively quickly and without technical help. e.g. unbootable PC, failed and replaced disk, ransomware... even user error. And the provide a full backup.
