Microsoft has been offering a new Preview of Windows 11 for a few hours. This build 25140 is available for PCs registered on the DEV channel of the Windows Insider program.
This is a Preview dedicated to optimizations and bug fixes. Microsoft explains that Windows 11 build 25140 comes with a “good set of fixes that improve the overall experience.”
The approach is not surprising knowing that the recent Preview versions of the OS have been accompanied by some new features. Microsoft has rolled out some much-requested updates including support for tabs in File Explorer. It is therefore time to optimize all this while correcting the latest known bugs.
Windows 11 build 25140, ISOs are available
One of the updates is to the glyphs available in the Euphemia font. The firm details
“The Euphemia font covers most languages that use Canadian syllabics […] In the latest Insider builds, we’ve updated this font to improve its readability and on-screen rendering of over 200 characters of various sizes. We have also added new glyphs to support Unicode 14 characters for the Canadian Arctic Nattilik language. »
For the rest we have fixes for File Explorer, Settings, Inputs and Task Manager. Being on the DEV channel, this Preview is not recommended for a production PC. It comes with several known issues. One of them causes a hibernation problem on Surface Pro X.
Surface Pro X devices experience a black screen when resuming from hibernation. You will need to perform reboot (power button extended shutdown).
Finally Windows 11 build 25140 is also offered as an ISO image. It allows a so-called clean installation, that is to say from scratch.
