• After installing this build, you may see a boot selection menu each time you reboot your PC. This is because a bug where a second boot option is persisted to uninstall the Windows 10 Technical Preview and roll back to the previous OS installed. When you get to this screen, if you do nothing it will automatically boot to the Windows 10 Technical Preview within 30 seconds by default or you can choose it on your own. Don’t worry, this behavior is only temporary.

• Xbox Live enabled games that require sign-in will not launch correctly. If you see the below dialog box the game requires Xbox Live sign-in. A fix for this will be distributed via WU shortly after the release of Build 9926.

• Battery icon shows on lock screen of PCs without batteries.

• Tiles on the Start menu show truncated app names (such as the Windows Feedback app).
