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.
