Win XP restore function 14 Q

XP's restore function has been used for so many years, is there really a deep understanding of this system? This article tries to analyze the system in depth for everyone, and see what secrets are hidden inside.

1. What is system recovery?

Using Windows XP's system recovery feature, users (system administrators and owners) can restore the machine to its previous state when they encounter problems. The System Recovery feature automatically monitors system file changes and changes to certain application files, recording or storing the status before the change.

With system recovery, users no longer have to consider saving snapshots for the system because it automatically creates easy-to-identify restore points, allowing users to restore the system to its previous state. Restore points are created when major system events occur (for example, when installing an application or driver) and are also created on a regular (daily) basis. In addition, users can create and name their own restore points at any time.

2. Which versions of Windows have system recovery capabilities?

Windows Me and Windows XP (Home and Professional). The following questions and answers are mainly for Windows XP.

3. What is the difference between system recovery and file backup?

System Recovery only monitors a set of core system files and certain types of application files (such as files with suffix exe or dll), records the status of these files before the change; and the backup tool is used to back up users. Personal data files to ensure that a secure copy is stored on a local disk or other media. System Recovery does not monitor or restore changes made to personal data files (for example, documents, graphics, emails, etc.).

The system data contained in the restore point of the system recovery can only be restored within a period of time, and the backup made by the backup tool can be restored at any time.

4. Does the system recovery require the user to open it?

No. Windows XP system recovery is automatically turned on, but at least 200M of available hard disk space is required. If the hard disk does not have 200M free space, the system recovery will be automatically disabled, and will be automatically turned on once there is enough space. By default, the system restores up to 12% of the hard disk space, and its "automatic restore point space management" will clear the oldest restore point, free up space and maintain the rolling security of the system recovery.

5. Will system recovery reduce system performance?

No. System recovery does not significantly affect system performance when monitoring system operating conditions. Creating restore points is a very fast process and usually takes only a few seconds. Regular system status checks (default is every 24 hours) are also only performed during system idle time without interfering with the operation of any user program.

6. Who has the right to use the system to recover?

Only users with administrator privileges can use system recovery to restore past system status or adjust system recovery parameter settings. However, the creation of a restore point is not related to whether the administrator is logged in. For example, when a non-administrator's other user uses the machine, System Recovery will still create a system checkpoint and an event-driven checkpoint, but the user cannot use the restore function, and only users with administrator privileges have the right to restore the machine state.

7. Does the system restore user data files such as WORD documents and emails?

No. System recovery does not monitor changes to user personal data files such as documents, graphics, emails, etc., and therefore cannot restore these files.
