Windows 10, 32 bit, Cumulative Updates Render Computer Useless

Question

Twice, I have had cumulative updates for Windows 10 Home, 32 bit render it useless. The updates in question appear to be KB5001330 and KB5003173.

In both cases the Windows logo appears, then the system halts, disk activity ceasing, and as I recall the spinning wheel of dots never appearing. After three attempts at starting and subsequent forced shutdowns, the Windows 10 recovery screen displayed.

The first time, I had to use System Restore to restore the computer to the state prior to the update being installed. The second time Windows itself restored itself to the state prior to the update being installed.

Hey Microsoft, I'm fed up with your cumulative updates transforming my computer into an expensive doorstop! Don't assume that just because a cumulative update works on 64 bit systems, it will also work on a 32 bit systems. Test it before you release it! If you can't get it right the first time, then outsource it to someone who can.

Hello there，

There are some known issues in this update KB5003173

System and user certificates might be lost when updating a device from Windows 10, version 1809 or later to a later version of Windows 10. Devices will only be impacted if they have already installed any Latest cumulative update (LCU) released September 16, 2020 or later and then proceed to update to a later version of Windows 10 from media or an installation source which does not have an LCU released October 13, 2020 or later integrated.

If you have already encountered this issue on your device, you can mitigate it within the uninstall window by going back to your previous version of Windows using the instructions here.

Please suspend your update for now. We are working on a resolution and will provide updated bundles and refreshed media in the coming weeks.

We along with other 32 bit Windows 10 users are also having the same problem with the the last three cumulative updates released by Microsoft.
