My wife started to complain that the laptop became slower. The laptop has a hybrid disk. I think I have found the cause. The clean at boot when the clean up was missed with the daily schedule. I had just randomly chosen a clean up time for the daily schedule, the system clean up seems to fill up the cache with useless (deleted) files. Are deleted flles written to recycle bin by any chance? System feels more responsive now (IE and Chrome launched with google search< 2 secs cold, 1 sec hot in stead of 3 to 5 it took before).
