You will not give a Submission that is subject to a license that requires Microsoft to license its Software or documentation to third parties because Microsoft includes your Submission in them. If you provide Microsoft comments, suggestions or other feedback about the Preview (“Submission”), you grant Microsoft and its partners rights to use the Submission in any way and for any purpose. Microsoft may not provide support services for Previews. Notwithstanding anything to the contrary in this agreement, Previews are nontransferable and provided “AS IS.” By installing Previews on your device, you may void or impact your device warranty and may not be entitled to support from the manufacturer of your device or network operator, if applicable.

We highly recommend that you do not install the Previews on any systems you don’t directly control or that you share with others. We recommend installing Previews on non-production devices that are not business critical because you are more likely to experience crashes, setting and policy changes, loss of data or apps, feature and functionality changes, cause other apps to stop working, be updated, or removed from your device automatically without notice and other potential issues. Because Previews may contain more errors or inaccuracies, you should back-up your device before installing any Previews. In some instances, you may not be able to go back to your prior version of the Software. To recover, you may have to reinstall your apps, the operating system or re-flash your device. In some instances, Previews may even inadvertently damage your device rendering it inoperable or cause occasional crashes, data loss or apps to stop working or be deleted. Previews are experimental, which means that Previews may not operate correctly and may be substantially different from the commercially released version. You may use Previews only up to the Software’s expiration date (if any) and so long as you comply with the applicable Windows License Terms. Microsoft may make preview, insider, beta or other pre-release versions of the Software (“Previews”) available to you.
