Microsoft has pushed out a new preview release of Windows 10 to the Windows Insider test community, delivering a number of bug fixes and a mysterious jump in build numbers since the last such release just a few days ago.
Windows 10 Preview Build 14251 has now been released via Windows Update to Insiders who have opted in to the Fast Ring to receive the latest test code from Microsoft.
The build does not contain notable new features for the operating system, but fixes numerous bugs as Microsoft adjusts the codebase for the so-called Redstone update due by summer 2016, which will be the next major upgrade of the platform following last year's Windows 10 November Update.
Gabe Aul, corporate vice president for Microsoft's Engineering Systems Team, explained on the Windows Experience blog that the jump in build number from the last preview build (11102) to 14251 is a readjustment to synchronise builds across the PC and Mobile versions of Windows 10.
"Because the mobile codebase used higher build numbers than PC, we needed to jump ahead a bunch of build numbers to ensure updates to future builds will continue to work. So that's why build numbers went from 11105, 11106 and 11107 to 14251," he wrote.
Aul said that this release fixes problems that some testers had experienced, such as File Explorer crashing when screen DPI settings were increased to 175 percent, or where some PC games crashed on launch when the user switched from windowed mode to full screen, or changed resolution, all apparently owing to a bug in the Windows graphics stack.
Microsoft informed its test community earlier this month that the criteria used to release builds to Windows Insiders in the Fast Ring will be much closer to that of Microsoft's own internal builds. This will see a more rapid pace of builds reaching Windows Insiders, but also lead to them seeing more bugs and other problems.
"We're at the beginning of a new development cycle for our next feature update to Windows 10, and that means teams will be checking in lots of new code as they integrate their feature payloads," Aul said.
"Being an Insider means you're getting the latest code changes, and working with new builds that are relatively new even for Microsoft employees. If this worries you, you can switch to the Slow Ring and stick with less frequent but more stable builds."
