This tip is awesome for me, under my special circumstances.
I've been loading all of my cores doing research and noticed the PC became unresponsive (including frozen mouse pointer) for about 5-10 seconds every minute or less. I tried turning off 'Get tips, tricks, and suggestions as you use Windows' (which is the new name for 'Show me tips about Windows', I had guessed). No more issues (other than than the normal sluggishness expected from having all cores loaded down).
I did not make any of the further changes suggested (e.g. uninstalling Windows Store Apps).
