Windows 10: whitelisting domains so updates still work
Posted by jpluimers on 2023/09/08
The internet access for my mentally retarded brother is fully based on whitelists.
It’s a simple reasoning: his mental abilities is basically a fixed box that does not grow. If he gains one part, he loses on another part.
This makes his risks assessments low and unpredictable at best, especially on the rapidly changing internet, hence whitelisting at the router level.
Whitelisting also implicates I need to update the ever changing list of domains that Windows 10 uses to keep newer versions up-to-date.
If you don’t, then you get an error [Wayback] 0xc1900223 while searching for or a applying updates. The description of that error isn’t accurate; what it actually means is that your computer cannot connect to one or more of the many update locations.
- [Wayback] Get help with Windows 10 upgrade and installation errors states:
Error What it means and how to fix it 0xc1900223 This indicates that there was a problem downloading and installing the selected update. Windows Update will try again later and there is nothing you need to do at this time.
- [Wayback] 20H2 Feature Update Error 0xc1900223 – Microsoft Q&A is more helpful:
The error 0xc1900223 may occur if your computer is unable to connect to the Microsoft Update servers or its content delivery network.
- [Wayback] Fix Error 0xc1900223 When Installing Windows 10 Updates » Winhelponline has a smart alternative that also makes updating a lot faster doing a major update (bit not minor updates):
Visit the Microsoft Windows 10 Download site. [Wayback]
- In my experience installing from an ISO image is often even faster (especially for updating one or many virtual machines) than with the “Windows 10 Upgrade” tool or “Media Creation Tool”. Force downloading Windows 10 ISOs instead of Media Creation Tool describes how.
- [Archive.is] How to troubleshoot Windows Update Error 0xc1900223? – Auslogics blog goes a lot deeper into the matter and (besides connection issues) also covers broken Windows Updater configurations.
These links should help finding the ones for newer Windows versions (at the time of writing, there was no documentation for Windows 10 21H1 or newer):
- [Wayback] Windows 10, version 20H2, connection endpoints for non-Enterprise editions – Windows Privacy | Microsoft Docs
- [Wayback] Windows 10, version 2004, connection endpoints for non-Enterprise editions – Windows Privacy | Microsoft Docs
- [Wayback] Windows 10, version 1909, connection endpoints for non-Enterprise editions – Windows Privacy | Microsoft Docs
- [Wayback] Windows 10, version 1903, connection endpoints for non-Enterprise editions – Windows Privacy | Microsoft Docs
- [Wayback] Windows 10, version 1809, connection endpoints for non-Enterprise editions – Windows Privacy | Microsoft Docs
- [Wayback] Windows 10, version 1803, connection endpoints for non-Enterprise editions – Windows Privacy | Microsoft Docs
- [Wayback] Windows 10, version 1709, connection endpoints for non-Enterprise editions – Windows Privacy | Microsoft Docs
Maybe one day someone makes an overview of these in one big worksheet to easily spot the differences. Until then it is a trial and error process every 6 months or so.
