After slimming with 360 system disk, the computer response becomes very slow. Refresh the screen, just flashing. Computer logo is normal, like copying logo.
It's impossible. Are you always like this? I have gained a lot after using it. It seems that slimming is just deleting useless garbage or backing up files. How can the system get stuck? Try to use the 360 system first aid kit. I think it may be temporary. The computer will be ready in a few days.
