The new version of Windows 10 Technical Preview brings along some great new features and many changes compared to the previous editions. However, as with any major release, there are a number of bugs and issues and you should be aware of these before taking the plunge.
According to Microsoft these are the problems you should expect to have with this latest build:
- 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. Donít 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).
- Remote Desktop has some painting issues that result in tiled pixelation.
- Connected Standby enabled devices like Surface Pro 3 may experience shorter than expected battery life.
- In Cortana, reminders canít be edited and more complex reminders might not get created. The first reminder you create in Cortana in this build might not pop up, but subsequent ones will. Completed reminders also donít move to the History page in Cortanaís Notebook.
- The Music app will disappear if minimized within 16 seconds of launch. Just leave it in the foreground for 20 seconds or so and it should work just fine.
- Occasionally, the Start Menu is improperly registered and will fail to launch.
Of course, that's not an exhaustive list. The whole point of this release is to see what works and what doesn't and fix things for future versions.
