Shareaza

This didn't used to happen, I think, under Windows 7 before I 'upgraded' to Win 10.
Anyway to configure Shareaza to make the opening seamless?
Or is this just a prompt to tell me to set Shareaza to open everything I start Win 10?
Thanks for help

Use regedit and go to "\HKEY_LOCAL_MACHINE\SOFTWARE\Classes\magnet" and delete that key, restart Shareza and open the torrent program you want and associate the magnets with it (most programs have this option).This is if you have already deselected in Shareaza itself to be the program for the magnet.
