Thinking of an end of year clean-up here.
I would like to clean my computer, and get rid of all the useless and unnecessary files. All remnants of uninstalled programs, and such. Also I want to clear the empty space - like defrag or better - on my computer and speed it up. In brief, I want to get rid of all the crap that is not needed.
I want to know how to proceed, safely, without deleting any system files that are needed to run the system.
I am on Windows XP SP3. I am very happy with it. I have no intention of upgrading until this laptop will live, I will keep the same OS.
I mainly have text, spread sheets and PDF documents, also a lot of pictures (mostly JPEG files) and some videos, and a fair number of MP3 recordings.
I would be very grateful if some of you can enlighten me on how to proceed.
Thank you very much in advance for any help and advice you come up with.
