14 DAY TRIAL // Microsoft has just announced a new Windows 11 preview build for the Dev channel, with the company focusing mostly on bug fixes and additional polishing.
Windows 11 build 25151 is therefore live right now for users in the Dev channel of the Windows Insider program, and in addition to some File Explorer fixes, including for a scaling issue that could make the tabs too large, there are also important fixes for the Start menu power controls and other crashes.
“We believe an underlying fix in Build 25145 addressed the recent issue where shutting down via the Start menu wasn’t working for some Insiders (unexpectedly rebooting instead), and as such are removing this from the known issues list. If you are continuing to encounter this issue with the latest updates, please report it in the Feedback Hub,” Microsoft explains in the official release notes of this new build.
“Fixed a high hitting Windows Security app crash. Updated the Exclusions page in the Windows Security app so that file paths now make better use of the available space rather than truncating when space is still available,” the company further notes.
Several known issues
Needless to say, there are also several known issues, including one that could cause the operating system to hit a BSOD after updating to this build.
However, Microsoft says the glitch has been around since build 25145, but a fix is yet to be released.
“We are working on a fix to address reports that the Mica material and Acrylic blur effect is not rendering correct in OS surfaces like the Start menu, Notification Center and other areas,” Microsoft says. “We’re investigating reports that some Insiders are experiencing bugchecks with error message KMODE_EXCEPTION_NOT_HANDLED in NetAdapterCx.sys starting with Build 25145.”
The full release notes for this build are available on this page.
