Here's what's been fixed and what's still broken in the Windows 10 PC preview 10122 build

The new Windows 10 PC Insider Preview build 10122 is making its way to Windows Insider members on the Fast ring. Microsoft has fixed quite a few bugs in this version compared to earlier builds but there are still some known issues that have yet to be addressed.

Windows Insider leader Gabriel Aul offered a list of what's been fixed in this 10122 build:

  • We have fixed the visual glitch ("rectangle slivers") that appears on Live Tiles on the Start menu with the new tile animation. In general, performance of the Start menu should be better in this build.
  • We believe we have fixed a lot of the crashes with Microsoft Edge (Project Spartan) reported by Windows Insiders.
  • Developers – when you go to Settings > Update & Security > For developers – it no longer crashes the Settings app.
  • We fixed the issue some people were seeing where their graphics driver fails to install from Windows Update with error code 80070103. This was happening because WU was trying to re-issue the driver.
  • You should now be able to edit the IPv4 properties of an Ethernet adapter on your PC.
  • We have fixed issues where fonts would render blurry on High DPI displays. We're cooking up a blog post we plan to publish shortly that talks a little more in depth about our investment with High DPI in Windows 10 so watch for it.
  • We have fixed some keyboard shortcuts in Microsoft Edge. Control + L or Alt + D shortcuts now got to the URL bar more reliably.

The list of known issues includes one that's already been mentioned about the Edge browser crashing when the build is used on a PC with AMD GPUs. Here's what else is still broken in the 10122 build.

  • Upgrading to this build on certain PCs may fail and roll back to the previously installed build with error 0x80070057 – 0x20007. This is a bug where too many device INFs are being migrated and hitting an internal limit. Possible workaround is to use Disk Cleanup to clean up system files and choose Device driver packages, Previous Windows installations and Temporary Windows installation files. You may also need to remove unnecessary peripherals and remove them from Device Manager and trying the upgrade again.
  • In this build there is a bug that may cause issues with Cortana speech. If you are experiencing problems with speech recognition, or are getting errors when trying to speak to Cortana, please visit this thread on the Windows Insider Program forum for assistance in recovering from this bug.
