Bugs

 * The BattlEye anti-cheat software has some incompatibility issues due to changes in the operating system between some Insider Preview builds and certain versions.
 * At the time of release, when attempting to upgrade to this build, it would fail with the error code 0xc1900101 and would subsequently fail as a result. Sometimes the installation of the build would complete on a second attempt.
