Now that the first Windows 10 Technical Preview of 2015 is out, we know many Insiders are scrambling to get it installed. Although, keep in mind that it is still early and unfinished software, so expect some bugs. Microsoft has also released a list of some of the known issues in Build 9926 of the preview.
Here is Microsoft’s list of known issues:
- 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).
- 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 can’t 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 don’t move to the History page in Cortana’s 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.
You may run into new issues yourself, and some may be unique to your specific hardware, but regardless, we suggest you report any additional issues to Microsoft.Further reading: Build 9926, Known Issues, Microsoft, Windows 10
