Win10 Update (live) using the install ISO

1. Mount it (from a location that survives reboots):
   • RT-CLICK the ISO file > "Open with" > "Windows Explorer"
2. Run Setup.exe
   • "Change how …" > "Not right now" (check box)
   • Next (button)
   • "Change what to keep"
     • Can leave unchanged; however, at version 1903, this results in a reset of many OS configurations back to their default; folder views, SendTo endpoints, shortcut (name and icon-overlay), ….
     • TODO: find what is changeable; find PowerShell script to handle this.
