Apple's iCloud for Windows users can't get the latest Windows 10 update because of nasty b...
Microsoft is actively preventing users of Apple's iCloud for Windows tool from updating Windows 10 to the latest build, with a new warning for version 1809 of the Microsoft operating system advising the iCloud software is not currently supported.

The status page for the re-release of Windows 10 version 1809 was updated with a new upgrade block on Friday afternoon, one that actively prevents systems running iCloud for Windows version 7.7.0.27 at all. As well as Windows 10, the block also applies to Windows Server version 1809 and Windows Server 2019.
Apple identified the incompatibility with iCloud for Windows, where users "may experience issues updating or synching Shared Albums" after migrating to Windows 10 1809. Microsoft claims it is working with Apple to produce a compatible version of iCloud for Windows 10 that works with the Windows 10 update.
For the moment, users who attempt to install iCloud for Windows on Windows 10 version 1809 will see the installation fail following a warning message that advises of the incompatibility. Windows desktops that have yet to be updated to 1809 are being blocked from upgrading until the issue is resolved.
Microsoft also recommends against users trying to manually update using alternate means, such as the Update Now button or the Media Creation Tool from the Microsoft website.
No timescale has been offered for the fix.
The re-release of Windows 10 version 1809 follows after the discovery the October update had issues where users documents and drivers were being deleted on their devices in some cases, an issue that was seemingly linked to OneDrive. A second problem relating to specific Intel audio drivers causing spikes in processor demand and battery usage, with a similar download block applied until the update could be fixed.

I don't think it's common, but when it does happen, you are seriously screwed.
We had an update on MrsRayz2016's laptop that knocked out the Wifi because of some incompatibility that the update introduced with the WiFi driver.
Mrs Rayz2016's sister fixed it. She's a wizard with Windows (I don't spend enough time with it anymore). Still, she had to plug the laptop directly into the router, then hunt around for odd bits of system file to repair the damage. It took her about six or seven hours, but she got it working, and we have a set of files we need to copy over after each update to keep it running.
Her next laptop is a MacBook Air, or her sister is going to have to move in.
On a note that may or may not be related is that I’m having external drive connectivity issues. Mac OS will not recognize them until it’s been plugged in for about 5 minutes. Windows will recognize it immediately but tends to disconnect and reconnect rapidly without heavy trial and error of keeping them connected on either OS.
i have tried multiple USB C to A adapters with a powered USB hub, so that can’t be the issue.

Note that this wasn't just about Apple -- Microsoft under Gates and Ballmer used the same calculus with their Windows customers -- just doing the minimum required to maintain the Office monopoly and no more.
I'll also add here that the world has changed, and I don't think Microsoft can quite as easily afford to piss off large numbers of Apple customers like they could back in the day...
I think Boot Camp also need an update, not just the iCloud software.
While I'd agree in general, it really depends upon how invested one is in the "Windows PC experience" and how open to change they are. Which typically gets less and less as one gets older.
Even on this forum, you see so many people who just can't get over the fact that the filesystem access on an iPad isn't the same as it is on a PC. It requires a new mental model which understands that individual apps host the documents (files) which they create/edit, and that you can use the share sheet to move those documents between apps, or send them to people. But if you're used to manually organizing your files into folders and searching for them using a file browser, then it takes being able to change your mental model.
