Quick answer
Treat Windows Insider use as a separate compatibility case. Preview builds can change shell interfaces before a customization tool adapts. Check release notes for the exact branch and keep a reliable path back to an unmodified desktop.
What matters for this task
The publisher history contains repeated fixes for Insider builds, which is useful context but not a promise that every new preview is supported immediately. A production workstation and a preview test machine should not share the same risk assumptions.
Steps to follow
- Record your Insider channel and full build number together with the StartAllBack version.
- Check whether the current release notes mention the relevant preview branch. An older Insider fix does not establish support for a later build.
- Use a test device or a recoverable test environment when evaluating new shell behavior. Avoid making a work-critical desktop the first trial.
- Keep the configuration minimal and record a short reproducible sequence for any failure, including whether the native shell also fails.
Verify the result
Test after each preview update rather than carrying forward an earlier result. Report the actual build pair and the smallest action that triggers the problem.
Limits and rollback
Disable the customization or return to a supported configuration when the preview and utility do not work together. Do not conceal unsupported-build warnings.
Questions about this task
Does “fixes for Insider” mean all preview builds are supported?
No. It refers to the context of that release and does not guarantee future preview compatibility.
Should I test experimental settings on my only work PC?
A recoverable secondary environment is a safer place to evaluate uncertain shell compatibility.
