1. You can delete the icons on the desktop, but I suggest that you don't uninstall some things that come with the system. It may be useless, but it won't take up too much space. If you want to restore the system, it is usually restored to the factory state, just like you just bought it back.

2. If you can't install the drive CD, you can disconnect from the network and try to install it. Or you can download the driver wizard or download and install the driver online.

The computer you just bought should have a genuine system. Please feel free to use. Even if it is pirated, there is no black screen phenomenon. Microsoft's last crackdown on piracy was aimed at xp, not vista.

If you want to restore the system, it is usually restored to the factory state, just like you just bought it back.

For newly purchased computers, cclean should be as follows:

1, cclean, right-click the properties of drive C, open the disk to be cleaned, click all the files of users on this computer, check everything in the cleaning options, and click Delete.

2. Right-click my computer properties, select System Protection under the task on the left, and then check System Recovery.

3. You can use vista Optimizer cclean to slim down the system.

If there is really no extra space, you can partition the computer disk again and set the C disk as large as possible.

This should free up four or five g spaces.
