The Windows 10 Fall Creators Update release to general availability is just two and a half weeks away, and as a result, Microsoft has ramped up the delivery of builds this past week, with no fewer than four dropping in a single week, if you count the skip ahead build too. And following Tuesday's build 16299 release to Insiders in the Fast ring, that same build has now been pushed to the Slow ring.
As a reminder here's what is fixed in this build:
We fixed an issue some Insiders were experiencing where after upgrading to recent flights their optical drive wouldn’t be listed under This PC.
We fixed an issue where Microsoft Edge might crash when scrolling embedded PDFs.
We fixed an issue resulting in some Insiders seeing 0x80070005 when trying to upgrade to the last few flights.
We fixed an issue where using the Automatic File Download notification to block an app from downloading files wasn’t working for UWP apps.
We fixed an issue resulting in Windows Defender potentially downloading files selected to be online-only after using the file picker dialog and viewing their thumbnails.
If you are in the Slow ring, you should be able to check for updates right now and install it by going to the Windows Update tab in the Settings app. This build includes desktop watermark and timebomb.
