I recently had to do a fresh install of windows 10 after a hard drive corruption, before the update win10 ran silky smooth with almost no lag, after the fresh install win10 takes 5 mins to open the setting panel, tried defragmenting my hard drive, no help, tried setting the amount of ram in the performance and appearance setting, im about to try a windows refresh to see if that helps, any ideas on what i can do to speed it up?
