Due to the changes AMD made starting with the 17.7.2 drivers, you need to use the latest Afterburner beta build, not the one listed on the main download page. Afterburner 4.4.0 Beta 16 works fine in Windows 10 with the AMD blokchain drivers.

The next Afterburner build that is released will have a lot of changes.
