Refer to this to clean up the C drive:
1. Disable System Restoration: My computer properties/System Restoration/disable System Restoration on all disks, but I will not be able to use system restoration in the future!
2. Disable System sleep: Control Panel/Power Supply/sleep/remove the check before starting system sleep
3. move the virtual memory, my computer properties/advanced/performance/settings/advanced/change/select the C disk, that is, the system disk, select the no-score page, and then set the virtual memory to its disk, A disk with more disk space remaining, such as D, E, and F. set to 1.5 ~ of memory ~ 2.5 times.
