Just today I was cleaning up a bit on my computer and deleting various files and programs. After doing so, I had roughly 97 GB of storage space left. However, upon looking how much space I had just a minute ago, I found that it had gone down to 93 GB, without me having done anything. No downloads, no changes, no nothing. Why is this happening and how can I fix it?
I also have another issue. The reason I had for deleting all the files to free up space was that it was really low at the time, around 3 GB. Simultaneously, my computer was running really slow and if I wanted to play a downloaded movie or something, it would be really laggy and slow. Is it possible that my computer running really slow could be due to low storage space? Slow movies is not the only problem, if I try to turn of my computer it stays at a screen saying "Preparing Windows configuration. Do not turn off your computer." for a really long time. What could the causes be for this?
Basically, what I would like some help with is:
Why is my storage space going down, without me doing anything?
Could the causes of my computer having become slower during recent times somehow be connected to how much space there is on it? (For example when it is really low, does that slow down the computer?)
