Today i upgraded Windows 10 to Insider Preview 17672.1000 (rs_prerelease) from the fast Ring.
Currently i’m got some troubles with starting that apps:
- xb.exe (eXtra Buttons)
- TuneupUI.exe (Avast Cleanup)
- AvastUI.exe (Avast Antivirus)
- OneDrive.exe / OneDriveSetup.exe
- Facebook App
- XING App
If you use one of them, and thinking about upgrading them, so better wait until the next build.

Edit: After a complete delete from all Avast Tools the Update works perfectly.
