because some software I use for my business is only available for Windows.....and for some reason, Windows 10 runs without any issues in Parallel, never had any problems with Windows 10 and Windows 7 before that.Sorry for the Off topic question, I'm a recent Windows to Mac convert and I am wondering, I converted to Mac because I was sick of Windows and wanted nothing to do with Microsoft anymore, as a Mac user, what makes you wanna use Parallels or anything from Windows?
1) You can safely upgrade to the latest version of Parallels. Your Windows installation will stay the same (whether in a file, or on a Bootcamp partition), but will update Parallels Tools.
2) Replacing iTunes with Music is one of the best things in Catalina. It just works. Your iOS devices are no longer handled via Music, but rather via the Finder.
