About dialog

Windows 10 build 20180 is the sixth Insider Preview build of Iron, the 21H1 development semester of Windows as a service. This build was released to Windows Insiders in the Dev Channel on 29 July 2020.

Changes[edit | edit source]

The new features that were introduced in build 20161 were rolled out to all Dev Channel Insiders starting with this build, however, they are disabled by default on clean installations.
The tablet posture logic for 2-in-1 devices has been changed to now only apply when using a single screen.
The new app folder icon on the Start menu has been adjusted to have a size more according to the rest of the icons.
The search boxes on the Default Apps Settings pages have received updates to improve performance.

Bugs and quirks[edit | edit source]

Some Microsoft Store games protected with Easy Anti-Cheat may fail to launch.
The update process to this build has a chance of hanging for extended periods of time.
The minimize, maximize, and close buttons can get stuck in their original positions if you resize a UWP app. A workaround is to move the window.
Some pinned websites do not work with the new taskbar experience.
The "close all windows" option in the taskbar sometimes doesn't close all the open tabs.
Live preview doesn't work for pinned site tabs.
Pinned sites don't show all open tabs for a domain. A workaround with this issue is to pin the site’s home page rather than a specific page.
Performing an Alt+Tab ↹ to a browser tab can sometimes move the previously active tab to the front of the Alt+Tab ↹ list.
Opening a WSL1 distro can give out the error "The I/O operation has been aborted because of either a thread exit or an application request".
