I had this video in my subscription box today and its basically a bunch of tips on how to speed up your computer and remove any unwanted files to free up disc space. I really found it handy and thought that i would post it, I recommend the HD version so you can see exactly what is being done but they explain the process well enough to where you just need to hear it. The whole process is using tools ur pc comes with and some other free ones from the web.
Idk how to embed the video so if someone could do it for me thanks.
u have to click HD under the video to view the HD version
