Laptop slow. How can I make it faster?

My PC is very slow although I almost never used it only for a few things at the weekend. I cleaned up with CCleaner yesterday, but it's still slow. What else can I do about it?

You could set it up completely. If you're ready to invest some money, you can also install an SSD. That makes an extreme difference for many.

Train him on a treadmill and increase more and more the speed that helps.

I do a disk cleanup about once a month with my laptop.
