Windows 11 build 28020.1495 arrives with WEBP support for desktop backgrounds and more

A new Wednesday build for Windows Insiders in the Canary Channel is now available for download. Microsoft released build 28020.1495 (KB5074168) with a bunch of fixes across the operating system and improved WEBP support. The latter now lets you set a desktop background WEBP image in the Settings app, something that Microsoft brought to the Dev Channel a few weeks ago.

Here is what is new:

[Desktop Background]

• In recent Canary builds, we added the capability to set .webp images for your desktop background in Settings > Personalization > Desktop Background.

Here is what was fixed:

[General]

• This update includes a small set of general improvements and fixes that improve the overall experience for Insiders running this build on their PCs.
• The desktop watermark should show the correct build number now.

[Start menu]

• Fixed an issue where the edge of the warning dialog shown when shutting down your PC while other users were still signed in was truncated by the edge of the Start menu.

[Input]

• Fixed an issue that could lead to a black flash when using a pen to ink in the Snipping Tool.

[Power]

• Fixed an issue in recent Canary builds that was causing shutdown to appear to restart on some Insider devices.

[Settings]

• Fixed an issue that could lead to the Windows Update settings page hanging when loading.
• Fixed an issue where language features under Settings > Time & Language > Language & Region for Australia (English – Australia) wouldn’t download (the button wouldn’t do anything when clicked).

[Other]

• Fixed an issue causing a small number of Insiders in recent builds to encounter bugchecks with IRQL_NOT_LESS_OR_EQUAL, related to the use of certain smart card readers.

Known bugs in today's update only include one thing:

[File Explorer]

• [NEW] We’re working on the fix for an underlying issue causing all open File Explorer windows and tabs to unexpectedly jump to Desktop or Home within File Explorer sometimes.
