Understanding the Upgrade Challenges
For those navigating the latest developments in the Windows 11 landscape, the transition from build 27686 to the newer release in the Canary Channel has proven to be a bumpy ride. If you've encountered difficulties during this upgrade process, rest assured that you are not alone in this experience. Microsoft has discreetly updated the release notes for build 27695 to address a significant issue affecting users attempting to upgrade, specifically citing a perplexing 0xC1900101 error that leads to a rollback to the previous build.
In the recent changelog for Windows 11 build 27695, Microsoft acknowledged the challenges faced by some Insiders:
[ADDED 9/5] We’re investigating reports that starting with Build 27686, when upgrading to a newer Canary Channel build some Insiders experience a hang at the boot screen and their PC rolls back with error 0xC1900101.
This 0xC1900101 error is not the only issue plaguing the Canary build 27695. Two other notable bugs have been identified:
- Copilot+ PCs: This issue disrupts Windows Hello PIN and biometric authentication, causing inconvenience for users relying on these features.
- Emoji Panel Glitch: Users have reported that the emoji panel unexpectedly closes when switching between tabs or selecting an emoji. Microsoft has confirmed this problem and is actively working on a resolution.
It’s important to remember that Windows 11 preview builds, particularly those from the Insider program, are not designed for mission-critical systems. The presence of the 0xC1900101 error serves as a stark reminder of the potential risks associated with using pre-release software, especially from the Canary Channel.
For context, Windows 11 build 27695 was introduced on August 30, 2024. This build brought several enhancements, including:
- A repositioned Widgets button on the left-aligned taskbar.
- Improvements to the Windows Local Administrator Password Solution (LAPS).
- A new “timebomb” feature for Canary builds.
- Refinements aimed at enhancing the Windows Update experience.
- Multiple bug fixes and additional features.
