Microsoft Windows used to be notorious for slowing down over time. A fresh OS install would restore performance. Many would recommend doing a fresh Windows install yearly to maintain performance.

I have a late 2012 MacBook Pro Retina with a SSD and unfortunately notice the same decreased performance over time with macOS. A fresh OS install breaths new life into the machine.

When you get your SSD do a fresh OS install instead of restoring the complete HD to the SSD.

Or just clean out your random LoginItems and kexts and whatever now and then. Check Activity Monitor and uninstall anything running that you don’t need.
