I was prompted to upgrade to Windows 10 from my Windows 7 desktop. After not seeing any performance increase, in fact, the cursor was moving in jerks and things were very slow. I looked at task manager and the IADataStorSvc was using over 50% CPU and 45% RAM. It does it pretty much all the time. I have searched other windows forums and this same issue came up with Windows 8 with no solution offered from Microsoft or Intel. I need some knowledgeable Microsoft engineer to tell me exactly how to remedy this and not blame it on a virus. This issue has been around for a couple of Windows versions and Microsoft needs to publish an explanation of what is happening and how to remedy it. I am (and have been) running Norton and I periodically scan for spybots using spybot.
