Almost at the end of the Windows 10 Fall Creators Update development, the Windows development team is certainly hustling. While there are no more new features coming up, the bugs and improvements and some new bugs are coming in a bulk this week. Microsoft has now started to roll out Windows 10 Insider Preview Build 16296 for PC. Today’s build is available only to Windows Insiders in the Fast ring, as the Skip Ahead has skipped forward to the Redstone 4 development. They won’t be receiving any new builds since the company is strictly focusing on the Fall Creators Update development right now.

#WindowsInsiders: nothing for Skip Ahead till mid next week as we are very busy with RS3 right now.
