Microsoft Windows 10 Creators Update Insider preview build 15042 is now available for Fast Ring Insiders. However, many Insiders are now reporting issues with the latest insider build.
Insiders are reporting issues like error 0xC1900401, Windows Update build 15042 hung at “Initializing…” or download stuck at 0%. Also, users are facing no audio, high CPU/disk usage, and Edge crash issues after installing the new build. We have posted some workarounds for these issues here.
During the 15042 install, your PC may “hang” and become unresponsive at the Windows boot logo screen. During the start of the install, one of the required processes may initialize but not complete or timeout, thus causing the “hang”.
Completing these steps will allow you to proceed and install build 15042 as expected.
When trying to download Windows Insider build 15042, you may see an error such as 0xC1900401, or a note that the build is not yet available for your device.
According to the Windows Insider team, there was a minor problem in the publishing pipeline. No manual efforts are required by Insiders. Insiders may scan for updates occasionally and as the update for your particular country/region is published, you will be able to download accordingly.

You can also repeat this process with the Delivery Optimization service(below). If stopping the WU service doesn’t bypass the issue on the first attempt, please re-try and stop this additional service.
If you fail to download Windows 10 build 15042 or your download stuck at 0% or at 95%, try the below-posted workaround.

To bypass this bug, please complete the following either the Quick OR Manual steps:
