Have you run some basic maintenance as this can often speed up a pc more so than of the so called cleaners.
Go to the control panel and look for Administrator tools. In this section run:
Disk Clean (you need to run it first to tick all the boxes of the options menu then run it again to actually cycle it)
Disk defragmenter
The look in the start menu for command prompt, right click on it and run as administrator. Type:
sfc /scannow
Press enter and await results.
