So I've got an HP laptop with a small 32gb ssd, and needed more storage to update to the latest version of windows. (8gb) I had 4gb of storage left to begin with, after deleting unused programs/HP bloatware. After that, I decided to compress the drive in the disk properties. after it was finished, I only had 2gb of storage. So, I tried uncompromising it, and had 500mb left of storage. I checked system restore, ran disk cleanup, and ran ccleaner with no success. Where did the storage go? There has to be some sort of backup somewhere, right?
