Looking at what it helpfully says for free, your main problem is windows search. That was my main problem on one of my machines. Nasty thing. And it is hard to uninstall, but can be disabled and its index minimised.
-WS has been a problem to me in more ways; the index is very seldom how I expect it to be. Sometimes, folders that I have manually added to be indexed, aren't, and sometimes they are. It's like my ex: "well, maybe I will, and then again maybe I won't!". From time to time I have used different search engines, but I have so far always returned to WS, because the others don't work quite like I would like them to. But I will see if totally disabling index will help - thank you!.
