Windows Dev Config: Disable Widget service errors on fresh Windows 11 PC

Start by reproducing the report on Windows 11 25H2 and inspect _registry.ps1 at line 43, then trace the phase 5 widget-service step. Review the phase 2 package checks and winget install handling using the reported Microsoft.WindowsTerminal failure. Done means a fresh setup no longer aborts at the widget step and package checks do not repeatedly fail with the reported error.

winver: Version 25H2 (OS Build 26200.9550)

I have freshly built a new Windows 11 PC, installed updates etc, then tried to run:

$url = 'https://raw.githubusercontent.com/microsoft/WindowsDeveloperConfig/main/src/windows-dev-config/bootstrap.ps1'
& ([scriptblock]::Create((irm $url))) -AllowUnsigned

This first 4 phases work as expected. During phase 5 it aborts on Disable Widget service.

I rerun the same command and then get errors in phase 2, this is repeated for all packages, showing only Microsoft.WindowsTerminal as an example.

I cannot share the original C:\ProgramData\CalmOS\devconfig-log.txt as a rerun overwrites the log file. Log header below.
