I don't understand. You don't know what to do. Is it because I broke my computer by installing qq music, or I really want to use qq music but I can't install it? If you can't install it, you can try it like this.

After checking the computer with 360, use the function on 360 to slim the registry (it can't be written, maybe there is something wrong with the registry), and then restart the computer installation. I don't know why you deleted those unknown files. In order to find the related content of qq music conveniently, it can be installed in the folder of any disk except C disk.

It is strongly recommended that you back up drive C and install a one-click recovery software for recovery.
