Another week, another build for Windows 10 Preview. This time, Microsoft pushed build 14951 to Insiders on both PC and Mobile. The new build brought a handful of improvements for various Windows 10 features, and fixed some of the known issues from the previous builds.

However, build 14951 also caused some problems of its own to users who installed. Microsoft already warned us about some potential problems in the build announcement article, but as usual, that’s not enough. In reality, there are many more issues bugging Insiders, than just those that Microsoft listed under ‘Known Issues.’

So, we wandered around Microsoft’s forums, in order to find problems reported by actual users, and we found a lot of them. In this article, we’re going to tell you about these problems, and try to solve at least some of them.

Windows 10 Preview build 14951 reported issues

It’s a tradition here at Windows Report to start our report articles with installation issues. Well, users have experience all sorts of installation problems when trying to install build 14951. Some of them reported installation fails, some reported stuck installation, while the build haven’t even show up for some users.

Here’s what Insiders said on the forums:

  • “Hi, windows updates is not showing nor downloading any windows 10 build 14951 for me. I tried to do it last night but wasent showing it so I decided to wait till today to try again and it is still not showing. Please could I have help to fix the problem?”

  • “I found the computer locked with 73% installed for 2 hours. I then did a manual restart and now the computer will not update.”

  • “Checked on my Surface Pro 3 running Build 14942 and it has not downloaded the 14951 update.  It appeared to be stuck downloading at 89%.  I kept an eye on it for a few hours with no change, I restarted Windows and it said the install was ready. Oh?  Clicked install and of course it didn’t work.  It offered a RETRY button which began the download again.  Stuck at 63%.  Same steps, same result. Third attempt is now at 90% and holding. Anyone else seeing an issue on the PC?”

Reportedly, the problem is already acknowledged by Microsoft, and we hope the company will fix it with the upcoming release. Until then, you can try resetting Windows Update, disabling your third-party antivirus program, or even skipping this one.

All these problems occurred on Windows 10 PCs, however, it looks like the same issue is present on Mobile, as well. Microsoft also acknowledged the problem immediately, and promised a solution to arrive soon. Here’s what Microsoft’s Jason [MS] said on the forums:

“We’ve just launched build 14951 to the Fast ring today and we’re seeing reports from users staying their device is not progressing past “0% downloading” on the update screen. 

We encourage Windows Insiders to file feedback or upvote feedback from others.  We’ve started digging through the logs we have already received to investigate the issue.

Now that we told you everything you need to know about Windows 10 Preview build 14951 installation issues, let’s see what bothers users who actually managed to get the new build installed.

One Insider reported on the forums that he’s unable to connect to internet in build 14951, regardless of the browser.

“The new build 14951 has the same problems as 14942/14946 : intermittent internet, many sites dont load up, if they did its garbage, bad full screen performance in games, bad video playback, etc. Once I roll back to 14936 , everything is fine.”

Unfortunately, no one from the forums had a proper solution for this problem. Microsoft will definitely need to pay attention to this solution, since it happens for a few builds now. We remind you that users mainly had problems with Microsoft Edge in the previous build, which apparently continues in build 14951, as well.

Issues with Windows 10 Enterprise mode are not so common in Windows 10 Insider program. However, we saw one in build 14951. One user reported that the latest three Preview builds broke DirectAccess. Here’s what he said about this issue:

“The last three Insider builds has broken DirectAccess.  I know that it is all functional on the server side, but I am unable to connect to any resources.  I cannot ping by name any resources on our network.  It has been forcing me to revert to prior builds until this gets fixed.  Anyone else having this issue?”

Other forum users have suggested some solution, but apparently, none of them worked. We also don’t have a proper workaround for this problem, so admins facing the issues with DirectAccess will probably have to wait for another build.

Another user have experienced problems with removing SD card from his SD card slot. Here’s what he said on the forums:

“there is system crash in ejecting sd card slot in preview build 14951…this issue did not fix in build 14951 … i experienced this issue in build 14946 … reported in feedback hub…is there any solution from the help community?…”

Since the Insider didn’t precise what kind of system crash is appearing, we can’t tell you about the exact solution for this problem. So, if you know something more about this problem, don’t hesitate to let us know in the comments below.

Now, let’s talk about problems that bugs Insiders on Mobile devices. Besides above-mentioned installation issues, there are a few more problems that deserve to be in our report article.

The first problem is the issue with display, which reportedly won’t time out for some users. Here’s what one user reported on the forums:

“Updated my Lumia 950 from latest production software yesterday, now after 10 hours of use i find out that screen won’t time-out and is still on. When i power screen off via power button then it doesn’t show glance, it’s turned off of course, but the problem is when i power the screen on again – it skips the lockscreen and shows start immediately, which means no Iris scanning, no PIN request, just open my phone to anyone.”  

Unfortunately, no one from the forums had a proper solution for this problem. So, if you know what users facing this issue should do, please let us know in the comments.

And finally, one user reported that he’s unable to download a new keyboard language pack on his Windows 10 Mobile device:

“After update to 14951 from RS1 14393.321 I tryed to download additional language keyboard. Same situation started as in 14946 – download stop on 0%, doesn´t continue. So I think there is problem with additional languages download”

Just like it was the case with the majority of problems reported here, other Insiders remained silent about this issue on the forums.

That should be all for our report about issues bugging Insiders in Windows 10 Preview build 14951. In case you’ve encountered some problems we didn’t list here, feel free to let us know in the comments.
