Hello everybody. I want to clean up in my PC case from dusts. What can i do? Thanks.
Thank you so much. I can’t pick up a best answer, all answers are best ^^

I want to delete all photos, pictures ect, but dont want to lose anything I need. What is the easiest way to do this?

I originally got McAfee free through AOL a few years ago, and I always got the free updates and stuff for years. Now I reinstalled Windows, and I want to get this McAfee back free. Anyway I can use the backed up files to do this???

actually is not free. In fact they wanted me to register but did not even tell me what it would cost. They indicated I had over 1,000 errors to be fixed on my computer. Why say it is free when it really is not free??? Is there any free system clean-ups?
