Loss of hard disk free space

i'm sooo not good at anything that has to do with technology. for example, had started post, bumped something ~ poof ~ disappeared. so i'll start over and hope my "other" post didn't land somewhere else on this site

here is my question / problem. the unused storage on my laptop shrunk by about 75% overnight ~ don't have a clue ... hence stumbling across ccleaner. now i see someone has said not to necessarily follow their deletion suggestions. a day late and a dollar short for me. is there a way i can undo whatever i just did? about an hour ago...

also ... does anyone have any idea why my storage filled up like randomly?

if i could afford it, i would just replace these damn things like once every 6 months and forego all of the time i waste and headaches i get trying to keep the damn thing "healthy"

any help would be appreciated...

I've moved your post here into it's own unique topic since it had nothing to do with the topic you originally posted it into.

What operating system are you using?

Hi, rrtt.

Won't help much with your present problem, but for the future consider an imaging software to keep a working backup of your OS.

Many folks here like Macrium. There is a free and a paid version. There are of course other options.
