For the last couple of weeks, my IE 11 has been getting slower and slower. No idea why. Other browsers (Edge, Firefox, Chrome) seem unaffected (but I simply have preferred IE in the past for various reasons).
Running on a Windows 10 Pro 64-bit system, Intel i7-3770k (3.90 GHz), 16 GB RAM.
Tried a few fixes I've seen on the web (KB3071338 fix, removing add-ons/extensions, etc).
