Windows 10 Technical Preview Build 10122 now available May 20th, 2015 Build 10122 is only available via Windows Update but it installs far quicker (less than half the time required to install previous builds).
What’s new: Start and Continuum improvements: We’ve further refined the visual layout of Start by moving File Explorer and Settings to the bottom left of Start next to Power and All Apps for better symmetry. In addition, the ability to toggle between Start menu and Start screen has been moved to the new Start settings page under Personalization settings.
Microsoft Edge: This build has the New Tab Page for Microsoft Edge that Joe showed off in April at Build. This page features a revamped layout, including top sites, featured apps and content from MSN. It’s designed to get you to your next destination on the web as quickly as possible.
Changes to how Windows 10 handles default apps: We know your defaults matter to you. With Windows 10, all apps – both Classic Windows apps and Universal Windows apps – will be unable to invoke a prompt to change your defaults, only Windows. You remain in full control of your default experiences, while reducing some of the unwanted noise that multiple prompts can bring.
Redesigned Insider Hub: The Insider Hub has gotten an overhaul in this build using a lot of the same design as the other Universal Windows apps included in Windows 10.
Here are some issues we have fixed
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.
