ok then
I suggest buying a second, spinning disk for your system, then move Photoshop's scratch operations onto it, along with data files, etc. You should have at least tens of gigabytes free on your C: drive for your system to be healthy.
Another option, depending on your system's capability, is to get another drive the size of your C: drive and create a RAID 0 arrangement with them. This both doubles capacity and throughput. Windows isn't going to get any smaller!
