Microsoft Announces Windows 10 Insider Preview Build 14251

Today, Microsoft releases Build 14251 Windows Insiders in the Fast Ring. In its official blog Microsoft states:
 
Sharp-eyed Insiders likely noted the big jump in build numbers from our last preview build (11102). Historically, the codebase for mobile had a different OS version than the codebase for PC because they were developed by different teams on different schedules. With Windows 10, we became one Windows team and brought these two codebases together. We started by changing the version string displayed in the UI to be consistent, which is why you saw similarly labeled builds over the past year for both Mobile and PC, but the underlying binary version numbers were still different. As part of our work getting the common codebase ready for the next release, we decided to complete that work and sync the build numbers between mobile and PC. 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.”
 
This build does not add any new notable features, but the company encourages its users to check the new Cortana improvements which were recently released, along with the Xbox Beta app. The January update for Windows 10 is now available with some improvements for insiders to try and give their feedback.
 
This build comes with some good bug fixes, which will be appreciated by the insiders. As per the official blog, they are:
  • The company has fixed the issue where some PC games would crash switching from windowed mode to full screen, upon game resolution change, or upon launch due to a bug in Windows graphics stack.
  • They have fixed the issue where applications such as Narrator, Magnifier, and third-party assistive technologies may experience intermittent issues or crashes.
  • The company has also fixed an issue where File Explorer would crash frequently when DPI settings were at 175 percent. 
Microsoft states:
 
“I also want to reiterate once again that with the change to release builds faster to Windows Insiders in the Fast ring, bugs like the ones we had in the last build (or the File Explorer copy UX from the prior build) are going to pop up. Sometimes it might be several builds before we get these bugs fixed. And there might be times where a build we release contains bugs we haven’t found in internal testing as well.”
 
Microsoft has also informed its users that they are at the beginning of a new development for the next featured update of Windows 10, and this means that the team will be checking numerous new codes as they integrate their feature payloads.
 
Microsoft states:
 
“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.”
 
Some of the known issues as per the official blog are: 
  • You might see a WSClient.dll error dialog after logging in. We’re working on a fix for this but as a workaround, you can run the following in Command Prompt with administrative rights: schtasks /delete /TN “\Microsoft\Windows\WS\WSRefreshBannedAppsListTask” /F
  • The Connect button does not show up in Action Center. The workaround is to press Windows key + P and then click “Connect to a wireless display”.
  • Due to a recent memory management change, you may see periodic app crashes or other memory related app errors. The workaround is to reboot your PC.
  • F12 Developer Tools will not load in Microsoft Edge. Should be fixed in the next build.
Gabe Aul, Corporate Vice President, Engineering Systems Team in the official blog states:
 
“I know that a lot of Windows Insiders are eager to know what’s going on with Mobile builds. As you know we’ve already released the Lumia 950, 950XL, and 550 devices with Windows 10 Mobile preinstalled, and we’re still on track to release Windows 10 Mobile as an upgrade to existing devices early this year as we planned. The team is working now by looking at data and reports from Insiders who have upgraded their devices to preview builds, and ensuring that we deliver a great upgrade experience to customers. We’re excited about making the upgrade available, and will share new information with you just as soon as we can on how the rollout will happen.”
