What's the difference between a one-click Restore and a reload system?

Now, many brand computers are purchased with a "one-button restore" function, so that we can easily in the computer failure to restore the system to the computer just bought back when the state, without having to install the system themselves. So what is the difference between a system that is restored with a single key restore and a system that we reinstall using the system installation CD? Which method is better?

The so-called one-click Restore, in fact, is a system full backup, restore program. It makes a full backup of the preinstalled operating system, which can contain installed drivers, software, and so on, and the backed up files are stored in a hidden partition or directory on the computer's hard disk. All we need to do is restore the contents of the backup before the computer is turned on to the system and follow the on-screen restore prompts for a simple operation. Because it's a full backup, we can only restore the system to a backup when we recover, usually when the computer buys it back.

The process of reinstalling a system is much more complex than a one-click Restore. First, it takes more time to install the operating system than to restore the system backup, and then, after installing the system, we need to install the hardware driver and the application software to get the computer working properly.

Therefore, in the early days of computer use, the use of a key to restore the proportion of the system simple and convenient. However, if the computer is used for a long time, one-click Restore may not be applicable.

As mentioned above, the brand computer is a key to restore the system backup is usually integrated driver and some OEM software, in the long-term use of these drivers and software may have some necessary updates and upgrades, and the operating system itself will have a lot of necessary patches need to be updated. And these drivers and software updates, cannot be updated individually to a single key restored backup file, so after restoring the system with a single key restore, you may need to do a lot of system update work, and some newer versions of the software may need to uninstall the previous version before you can install it.

Updates to systems and software can take a significant amount of time and effort, and can be compromised by viruses or malicious programs if the operating system connects to the network without fully installing all the patches. Instead, reinstall the system directly using the new version of the system that integrates the updated patches, and then install the latest versions of the driver and application software directly.

Of course, most of the one-click Restore program also provides the ability to back up, we can use the new version of the system and software reinstall the system to back up for later use.

Finally, to remind you that, whether a key restore or reinstall system, the system partition (usually C disk) above all the data loss, so be sure to remember to install or restore the system before the important data are back to other partitions Oh!
