Microsoft has released Windows 11 Insider Preview Build 25140 to Windows insiders in the dev channel.

Announcing Windows 11 Insider Preview Build 25140

Hello Windows Insiders, today we are releasing Windows 11 Insider Preview Build 25140 to the Dev Channel. 

Changes and Improvements

[General]

• Euphemia typeface covers most languages that use the Canadian Syllabic script including various Cree orthographies, Inuktitut, and the Carrier/Dakelh script (dulkw’ahke). In the latest Insider builds, we’ve updated this font to improve the legibility and screen rendering of over 200 characters at various sizes. We’ve also added new glyphs to support Unicode 14 characters for the Nattilik language of the Canadian arctic.

Fixes

[File Explorer]

• Fixed an issue which was leading some people to unexpectedly see error 0x80070026 when copying files from network drives.
• Fixed an issue where the active tab color didn’t match the command bar below it.
• Fixed an issue where dragging to rearrange tabs wasn’t working sometimes.
• Fixed an issue which could cause artifacts in the windows thumbnail preview in the taskbar if File Explorer was maximized and you used WIN + M to minimize it.

[Settings]

• If you go to rename a drive label in System > Storage > Disks & Volumes, the current drive name will now be prepopulated in the dialog.

[Input]

• Fixed an issue where selecting English (New Zealand) in OOBE was unexpectedly leading to the Arabic (101) keyboard getting selected.
• Setting language bar hotkeys for switching input directly to specific non-IME input method should work now.
• Some languages don’t support the speech recognition FOD. When an admin user tried to install one of those languages using the new Install-Language CopyToSettings command, some settings such as new user account locale, Input (Keyboard), and UPLL (User Preferred Language List) were not getting updated. This issue has now been fixed.
• Fixed an issue causing Batang, BatangChe, Gungsuh, and GungsuhChe fonts to not render Korean correctly when using Office online apps when these fonts were not locally present on your PC.

[Task Manager]

• Fixed a crash that could happen when switching modes in pages other than the Processes page.
• We made a small adjustment to the intensity of the colors used in the heatmap on the Processes page.

[Other]

• Fixed an issue where calls to  CopyAcceleratorTable and  CreateAcceleratorTable would fail if the LPACCEL parameter was the address of an odd numbered index into an array of ACCEL structs.
• Fixed an issue with x64 emulation on ARM64 which could result in certain apps crashing on launch with error code 0xc0000409.
• Fixed an issue causing audio to stop playing in certain apps after a minute.

NOTE: Some fixes noted here in Insider Preview builds from the Dev Channel may make their way into the servicing updates for the released version of Windows 11.
