How long has Webroot been compatable with windows 10?

Hello ?,
 
i would say Webroot has been compatible since the release of Windows 10. 

I think that WSA has been Win 10 compatible since well before the official release of Win 10 given the exhaustive beta testing carried out by the Community members who where also part of the initial Windows Insider program, i.e., Win 10 pre release testers...and that went on for some month prior to the official release date for Win 10.;)
