Two download issues found and solved

In addition to the platform related bugs the new build experiences, Insiders also ran into issues when attempting to install build 15019. Microsoft has already offered some solutions to this problem, with Jason Howard of the Windows Insider Engineering Team posting two issues to the Answers forum.

The first issue is ‘Error 0xC1900401' that may appear when you try to download the new build. Howard has posted the workaround which is the following: “There was a snag in the publishing pipeline.  No manual efforts are required by Insiders.  We have found the publishing issue and are remedying it.  You may scan for updates occasionally and as the update for your particular country/region is published, you will be able to download accordingly.

Concerning issue #2, some users' PC scans and finds build 15019, but “it appears to hang on “Initializing…” and doesn't appear to begin downloading the build.” Howard gives Insiders the solution to this issue, which requires them to follow seven steps:

  • Click the Start button
  • Type services and launch the Services panel
  • Scroll to Windows Update
  • Right-click and select Stop
  • Restart your PC
  • Re-check for updates
  • The update should proceed as expected.
