I have a PC laptop running windows 10 and Photoshop CC 2017. It is over 2 years old, and has 8GB of RAM. Its hard drive has 432GB free out of 465GB. The last time I shut down was earlier today. I run a cleanup program about once a month.
PS: I know I need to free up storage space. Dangerously full, have backed everything up and am going to cull this weekend.
