You can change it yourself. You back up everything in the original C disk to another disk (mainly the folder of tax control software, which contains information such as the products of the company you have issued a ticket, which is a pity), and then call them for free door-to-door service. He said that if the data is lost, don't give him the bird. Show him the backup folder (invite him to dinner at noon at most). What is that called spatial information? Nigger vampires are shameless, but those who come out to defend them are not good at all. Poor thing. You said you would pay the service fee for next year, and he would be happy and leave you alone.
