Hi,
Just to mention that,not related to Sonar only but with other softwares( Ardour,Vegas and maybe others),
Win10 works really fine here,it runs hardware with XP drivers with no problems ...BUT it seems that Windows defender puts everything upside down.
So as far as remaining on line with firewall and defender disabled is somewhat scary !!!!
My turnaround is to stay offline with everything disabled ,and go on line every week to stay updated.
Things like Voxengo Pristine Space bridged with Jbridge make all softwares crash with defender enabled and everything is ok when it is disabled .
The same with Xln installer and other random issues....
Sorry if this post is outdated...
All the best.
