OK!! Did the whole thing,defrag,adware,dumped cookies,created a restorepoint and ran jv16 on aggressive mode.
Restarted FS and ran harsh weather(definitely kills frame rates for me)-not a flicker. Overall everthing is a lot quicker,startup(cold computer)is better and loading FS was a breeze.
The task manager showed FS running at 75-80% where before it was peaking 100% with heavy weather(I normally select downloaded weather).
All this is subjective of course but since I use this thing every day for at least 7hrs I think it is a valid observation

Wonderful!!
