With a good modern internet connection that should take a few mins at

for me maybe 5 at most


It took me almost an hour to dl the last update and I have a fast
connection, over 200mbs.
Why? Because it wouldn't dl all at once. It would stick at different
percentages for a long time.
Is their a link that you an dl from without using the MS Update site
built-into Win10?


You can adjust the process priority to break deadlocks,
but I'm not at the point of delivering "recipes" on this.
I'm still trying to figure out why it is broken.

Several Insider editions ago, the Settings control panel
stopped updating. So you'd see "20%" and the thing was
still doing downloads, but the number would not change.
That seems to be fixed now. But some other stuff behaves
in a weird fashion. I tried bumping TiWorker (or equivalent),
I tried changing the priority of the SVCHOST with wuauserv
in it. What I noticed, is the Delta downloader "productivity"
drops with time. Initially, it might be using 40% of a core,
then gradually the CPU load drops to almost nothing.

I don't really think process priority ("Above Normal") is all
that good of an answer. What I was looking for at the time,
was something to "bump" the process and get it going again.

I've had weird behaviors on Windows before, where merely
opening Task Manager dialog on the screen, bumped things
enough to get them running again. But so far, with the
Delta downloader, I haven't figured out why it slows
down (or stalls).

Rebooting when this happens is convenient, but the
Delta Downloader does not "checkpoint" its progress in
Win10. So the percentage done will drop back to 7%. It
seemed to "recompute" the download, and resolve the
downloads using the files it already has. So it won't toss
all the downloads it did away. But it will annoy the hell out
of you with its slow slow behavior (in all cases).

You'd swear Microsoft had investments in power generation
companies, for all the electricity this is wasting. I've
never seen so many CPU cycles just... wasted.
