My Acer has an Atheros wireless adapter and W10 has always taken around 2 hours to install because of a faulty driver. I started reporting this back to MS nearly 3yrs ago.
On the Acer I found much later that pressing the WiFi button a few times at the appropriate point in the installation seemed to disable things and the process speeded up.
The problem was still not solved even with the CU and I had to go through the same performance again.
So far every cumulative update for 1703 has hung at 1% or 2% for me. That seems to be because I have a metered connection set. For other updates like Defender definitions, checking for updates responds correctly saying: 'can't download while on a metered connection' and offering a 'download' button.
This doesn't happen for Cumulative Updates, instead it starts downloading then stops at a few percent, never to go any further. Turning off 'metered connection' invariably lets the download continue then run to completion.
This would appear to be a failed implementation of the revised wording in 'Settings - Windows Update' that appeared with 1703.
Being curious (and with time on my hands) I got my test machine (15063.483) to check for updates on a metered connection, then waited to see what would happen. It duly found KB4032188 and went straight to 'downloading', crawling painfully slowly to 1% then stuck at 2%. Task Manager showed it was actually downloading something occasionally over the WiFi , but not much and not very often. I presumed these were the few bits that MS deemed 'required to keep Windows running smoothly'.
I waited (and waited) to see what, if anything, might eventually get installed - nothing, it turns out. Instead, after waiting quarter of an hour it eventually gave the 'Updates are available. We'll download them when you are not using a metered connection' message and the 'Download' button.
Instead of clicking 'Download' I restarted the PC, just to see if something got installed after all. Nothing, but some part of the update had obviously been downloaded (though not installed) because when I checked for updates again it skipped straight to the message and the 'Download' button.
Curious. Why would it have downloaded something it can't then install? 1703's new idea of overriding metered connections to 'download only those updates required to keep Windows running smoothly' still seems to be a 'work in progress'. :)

So on my 12yr old Dell today finally got around to doing the clean install of CU next to my existing AU 1532 which goes back to Windows 7.
Boot and install from USB drive on my 2nd SSD went surprisingly quick, and after a few restarts everything was up and running with no issues whatsoever. Just in case I had disabled the Broadcom NIC in the BIOS. First install (despite it looking and finding Updates in the process) identified itself as 15063.0, but after another round of WUs that got stuck at 17% upon which I manually restarted, it booted into 15063.502. Enabled the NIC and as expected the Broadcom issue is fixed. Doesn't come as a surprise that the new CU feels a bit "snappier" overall than the old AU. Next course of action will be to leave the old junk behind and migrate from AU to CU.
This is what the boot manager looked like right after the install.

Think we shouldn't consider it as a problem, Windows 10 is the problem. Even managed to reproduce those errors on a freshly installed virtual Windows 10 without any other software installed at all. Think it is just an initializing-thingie. One of the things 'solved' in this update has to do with those stupid store and apps, after all...As said it appeared only once, would be more 'worrysome' if the errors where there every boot AND had an influence on system stability. Which is not the case. Only general advice I can give is: avoid installing store apps at all. Delete the apps you can delete. It will make Win 10 start smoother without daily app-updates that regularly don't work out that well... Hopefully Microsoft will also realize that the Store is a fail and adds a lot of unnessary troubles for users. Besides, what is offered in matter of apps is mainly useless junk anyway.

Same here on 3 laptops, even created a separate thread: KB 4032188 issue...
First time I have a problem with W 10 updates, no matter of the build.
