Microsoft released the new build 14393 for Windows 10 Preview and Windows 10 Mobile Insider Preview a couple of days ago. As the Anniversary Update nears, some people started thinking this build will be the Anniversary Update RTM, as it didn’t contain many known issues revealed by Microsoft.

On the other hand, users usually have something more to say about a new build than Microsoft notes, and build 14393 is not an exception. So, we wandered around Microsoft’s forums searching for problems in this build, reported by actual users, and in this article, we’re going to tell you what really is going on in Windows 10 Preview build 14393.

Windows 10 Preview build 14393 reported issues

As usual, we start our report with installation problems. It looks like no Windows 10 Preview build can go through without causing various installation problems to at least some users.

“I cant update my pc to last build 14393 from current build 14372. I set all setting for insider fast. after cheking for update my pc say upe to date. but my phone build vesion is now 14393. help me for update to last build,” said one user on Microsoft’s community forums.

Additionally, even Windows 10 Mobile Preview Insiders reported the same issue on their Windows 10 Mobile devices, along with additional WiFi problems:

“When I update 10.0.14393.0 in my Lumia 540 dual sim at that downloading update 36% complete after that download update stop. I wait 3/4hr but doesn’t download. After that i notice my Wi-Fi doesn’t work( doesn’t connect in my phone). I try to connected WiFi lot off time but not connect. And I really surprised before update my internal memory 4.78 Gb but without full update(100%) without install and without migrate data my phone internal memory now 5.44Gb. How can it possible?”

Speaking of WiFi problems, users also complain about networking issues on their PCs running the latest Windows 10 Preview build:

“I installed build 14393 PC version last night, with this build there is no network access due to IPv4 and v6 sockets had no internet access. I could not even ping my router.”

Unfortunately, Microsoft engineers and other users of the forums didn’t have a proper solution for this issue. If you’re encountering networking problems upon installing build 14393, as well, we can recommend you to check out our article about internet problems in Windows 10, but we can’t guarantee solutions will surely work.

Sound problems were more common in earlier Windows 10 Preview builds last year. However, it looks like these issues started to appear again, as one Insider reported that sound on their computers stopped working upon installing build 14393.

“I cannot get sound out of my usb speakers after windows 10 install. I have tried everything”

We have to mention that user who reported this problem didn’t precisely say it is related to the latest Windows 10 Preview build, so we’re not entirely sure this issue was caused by build 14393. All in all, if you also encountered sound issues in the latest Preview build, please let us know in the comments, so we can confirm this issue is indeed caused by the build 14393. You can also check out our article about audio problems in Windows 10, in case you need any help for this problem.

Next, one Insider reported that he’s unable to receive emails to Outlook 2016 in build 14393:

“Since I downloaded build 14393, I have not been able to get my email from the server. It is stuck on Monday 8:38 am when I last check my email. I check my email settings and come up with an error code: The server responded: 552 5.2.2 users mailbox. What has happen?”

Once again, engineers and other Insiders weren’t so helpful, so if you’re encountering a problem with Outlook in the latest Windows 10 Preview build, try running the Recovery Assistant for Office 365 tool, it might help.

One user also reported a problem with Microsoft Edge extensions in Windows 10 Preview build 14393:

“When I load an extension, left clicking the extension button does nothing”

Issues with Microsoft Edge extensions in Windows 10 Preview builds are quite common, so we hope Microsoft will improve the stability of this feature once the Anniversary Update gets released.

Now back to Windows 10 Mobile Insider Preview, where one user reported that his Lumia 550 can’t recognize a SD card in the latest Preview build:

“I installed build 14939 on my Lumia 550 last night but since then my SD Card is not detected. Is this a known problem and/or does anyone have a solution to this problem? I’ve already tried reconnecting my SD Card several times, but this had no effect.”

There are even some users who said multiple problems in Windows 10 Preview build 14393. For example, one Windows Insider said on the forums that the latest build caused problems with Home Group, dual boot menu, and Sticky Notes. Unfortunately, a confirmed solution for all these issues is still missing.

This concludes our article about user-reported issues in Windows 10 Preview build 14393. Even though we wrote about a lot of recently reported problems, that doesn’t mean we covered everything. So, feel free to let us know in the comments in case you’re bothered by some issue we didn’t mention in this article.
