If you’re looking to invest in a good registry cleaner then I highly recommend looking into a great little program called RegCure.  I stumbled across RegCure after doing some research into the best registry cleaners available.  I read a really positive RegCure Review so I decided to check it out.  Turns out that this program worked very well on my computer, clearing more than 700 registry errors in a short amount of time.  I personally think that this program was what helped me reduce the total boot time of my computer.  The startup manager is also a great help when trying to speed up your PC.
