Acronis True Image does not support Windows Insider Program builds (beta builds of Windows). Although, Acronis True Image usually works on beta builds, you might experience issues when using our software with these versions of Windows.
As stated in the Windows Insider Program Agreement, Windows Insider program participants are volunteers who receive experimental and early pre-release software. This means that these new builds of Windows that you receive through this program are still in development and testing and are not production-ready yet. These builds are not as stable as the official release builds are and may have issues that affect the software installed on these Windows versions. During the test period, Microsoft fixes many of the issues within the operating system and thus the software issues may be resolved as well.
We do test our software on beta builds internally, however, thorough tests are made on the late beta builds and release candidate. For Acronis True Image, we can state the official support of a new Windows OS build only after its official release.
