6. Last but most of all not the least. Auslogics boost speed. Now this program only runs you on a trial basis for 15 days, I would recommend you get your use out of it then uninstall if your like me and don't want to pay, but if you do its your choosing.
Here's the link, http://www.download.com/Auslogics-BoostSpeed/3000-2094_4-10358299.html?part=dl-10358299&subj=dl&tag=button&cdlPid=10992276
Now install and use all the components you want that the program has to offer, I recommend one button check up, advanced registry scan, and the registry defrag here if you haven't already. The track eraser and disk wiper are also nice, I would stay away from the memory optimizer and internet optimizer functions because they are not that effective, and annoying in some respects, but everything else is pretty solid. Don't be afraid to check all the options under advanced registry scan, also be careful with the disk cleaner, because disk cleaners in general are pesky at removing things in some instances that you would prefer not to be removed. Enjoy!
