I have a mini laptop which kept giving me low disk space warnings. I blamed it on Windows updates. But, when I took time and looked into the memory, I found a different culprit. It was HP Tools. The system restore files had filled all the available space on the drive E. Once I deleted them and set it to not continue saving restore points it stopped warning me about ultimate destruction and general doom and gloom.
So now I have my mini laptop back. Hooray!
