Found a simply magnificent MS reference thanks to the great folks at TenForums today.

It’s especially informative for those seeking insight and possible fixes for upgrade issues and errors.
Trust me: This innocuous title does no justice to the Guide’s many treasures.

Windows 10 Upgrade Errors Explained
Let me help to make sense of this gem. Please understand that Level 100 is Basic, 200 Moderate, 300 Moderate advanced, and 400 Advanced in terms of technical level. In fact, the actual entry that caught my eye was the one for error code 0xC1900101. It includes a raft of tried-and-true techniques for avoiding errors that sometimes occur during the upgrade process. Among other good suggestions, these include:
- Uninstall antivirus applications beforehand
- Remove all unused/unnecessary SATA devices
- Remove all unused devices and drivers
- Update drivers and BIOS, especially the graphics/display driver(s)
- Disconnect all peripherals except keyboard, mouse and monitor
- Take the “Download and install update updates (recommended)” offer at the outset of the upgrade process
Great stuff. I’ve learned, used, and needed every single one of these exhortations over the years. Add this Guide to your bookmarks or favorites. You’ll be back!
