3. What is system restore and why is it useful?

   • System Restore is a feature of the Windows operating system (starting with Windows ME) that allows users to restore their system to a previous point in time. This restoration includes, but is not limited to, the following types of data: system files, installed applications, the Windows registry, and system settings. As you can guess, system restores should not be taken lightly, but they can be extremely useful in the right circumstances.

4. What is system information and diagnosis?

   • System information: The operating system keeps a record of all the hardware and details of the operating system such as make, clock speed, number of processors, version numbers and so on. It does this by using a 'system information' utility. This is very useful for people when they need to know the details of the system, perhaps to see if an application they are considering getting will be compatible. Diagnostics: These utilities will test the system to see if there are any problems. For example an utility called 'chkdisk' on a windows system will run a number of tests on the hard disk to see if it working properly.
