We tested Bet Angel on a pre-release candidate of Windows 10 and it worked well. We have since tested it on a full release and it also works very well. Obviously you may experience driver issues with the Windows 10 upgrade but once they are sorted there is no reason for Bet Angel to fail.
One word of warning. Some Anti-virus and security software can cause an issue when you first reboot into your shiny new Windows 10 screen. We advise you to uninstall any Anti-virus and security software prior to the upgrade and re-install it upon completion.
