CCleaner will help a bit.
Malwarebytes, yes, if you have some nasty shizzle on the laptop.
As your laptop is 4/5 years old I am guessing there is a chance it is still XP, if so then ssd is a deffo no go imo.
Again, if XP, then the only true way really to get it back to normal would be a fresh install really. If Vista then fire and magnets tbh.
Personally, a fresh install and if possible avoiding all the bloatware would be best.
Thanks, it is Win7 with an i3 core, but all I really use it for is to save photos and as a Chromebook
I ran Ccleaner and Malwarebytes, both were really easy to use, even for an idiot like me.
I just clicked scan, fix, scan, fix, scan, fix, scan, fix, scan, fix even for the Registry stuff and it seemed to do it no problem, nothing seems broken yet...!
