Within the last 6 months when I try to play music and use my desktop, simultaneously (it doesn't stutter if I only listen to my playlists) , I have been incurring "stuttering" of the playback.  At first it was sporadic, but overtime t has increased infrequency to a point where it now occurs on every song sometimes repeatedly. I have tried all the "Google" remedies and some Apple remedies as well, to no avail.  I have exhausted Apple iTunes support and they say nothing is wrong on "their side."  I have an extensive music library consisting of purchased music and music downloaded from my personal Vinyl collection and CD's. I am using the latest iTunes software and I have the most recent Windows10 on my PC.  Please help.

Please note, I am a Tech Luddite so please be patient and reply as if you are writing another chapter of "Computers For Dummies"

Thank you
