Windows 10 build 16291 bugs in Slow Ring: install fails, black screen issues, and more

Microsoft will roll out the Windows 10 Fall Creators Update in just three weeks’ time. As a result, the company is working at full speed to add the finishing touches to the OS.

The Redmond giant recently pushed out Windows 10 build 16291 to Slow Ring Insiders, but it seems that this version of the OS  is quite unstable. Insiders reported that Microsoft failed to fix some of the bugs that affected the build when it was first released to Fast Ring Insiders.

If you’re planning to install build 16291 on your PC, read this article to learn what its most frequent issues are.

Windows 10 build 16291 reported bugs

Build 12691 install fails

If you can’t install build 12691 on your PC, you’re not the only one: many users reported that the install process often crashes during the reboot phase.

I cannot install RS3 16291 install ’cause it crash at 6% during the “reboot” phase.
I’ll try to clean Windows update/software distribution and try again. !

Other Insiders reported that error 0x80070057 prevents them from installing the latest builds. The only way to fix this error it to clean install Windows and then download and install the build again.

EVERY insider release since 14.x on my Surface pro4 I get this bleeding bip error…. ( Error 0x80070057 )It ends up with me having ALWAYS to fresh install windows and delete all apps and more.. then it will install.. It is VERY frustrating to say the least!!!
And I have tried every troubleshooting on the internet… WHY can’t MS fix this!!!

Touch keyboard language settings issues

Full XAML touch keyboard support for all languages is still unavailable. Also, the swipe feature works smoothly with US English keyboards only.

When can we expect the full XAML touch keyboards for all languages with a keyboard? There is still after all this time no full keyboard for Myanmar script.
When can we expect swipe to work for keyboards other than US English? It still fails to work for English (Australian) and isn’t even available for English (International), let alone other languages

Builds resets Windows user settings

Many users complain that the build resets user settings:

After the update to build 16288 and 16291 all user settings have been reset to default. It is as if the user logs in for the first time after a fresh windows install. This also occurred after the update to build 16291 (from 16288). This never occurred in past insider builds. Anyone else had the same experience?
Update: I installed build 16291 on 2 PC’s and on one PC the user settings were saved, while on the other PC the user settings got reset.

Black screen issues

The latest Windows 10 builds causes black screen issues for many users, and build 16291 is no exception.

The last three builds, when I’ve tried to update, have booted to a black screen with cursor, after the first update reboot. […]  I quickly see a window pop up and disappear before no further progress is made. Then I have to hard reboot. In the upgrade version, it gives me a Safe_OS installation phase failure error.

These four issues are the most frequent build 16291 bugs reported by Slow Ring Insiders. If you’ve encountered other issues, let us know in the comments below.
