Bugs and quirks

 * You must use an IDE or SATA hard drive if you want to install this build in VMware, otherwise the setup won't be able to find the drive.
 * The BattlEye anti-cheat software has some incompatibility issues due to changes in the operating system between some Insider Preview builds and certain versions.
 * The cloud download recovery option is broken and thus it can't be used. The local reinstall option must be used when using the Reset this PC feature.
 * The update process to this build has a chance of hanging for extended periods of time.
 * At the time of this build's release, some Windows Insiders were unable to update to this build and instead got an error with either the error codes 0x8007042b or 0xc1900101.
 * When certain external USB 3.0 drives are attached, they stop responding with Start Code 10.
 * The documents section in the privacy settings has a broken icon, and as such, a rectangle shows in its place.
 * The IME candidate window for the East Asian IMEs (like the Simplified Chinese, Traditional Chinese, and the Japanese IMEs) sometimes does not open. If this bug is encountered, change the focus to another application or text field and back to the area that was being originally worked on. Ending the process  via Task Manager can also workaround this bug as well.
 * At the time of the build's release, there was a bug that prevented ARM64 devices from updating to this build successfully.
