Very recently my windows has begun to stutter, visual media players (Games, Youtube, etc) will stutter and so will audio. But I know it is Windows itself as Windows sounds stutter as well.
I presume it's software-related and I have observed this change since it begun:
Windows Update, I assume I have gotten a windows update that has caused this, as I see Services in my process tab and a GPU engine tab.
I have tried updating my graphics driver & scanning for virus.
