The system can develop problems due to erroneous operation or the installation of
additional software. If software problems develop in the originally installed software,
you can restore the system by using system backup and restoration features.

  Note: The existing system settings will change after restoration. Check the

settings of the restored system to ensure they match settings that may be 
critical to your needs.

Use the following procedure to restore the software to a known functional level:
1.  Click Start 

→ All Programs → Accessories → System Tools → System 

Restore.

2.  Choose either the recommended restore point, or select a different recovery 

time from the pop-up box. Choose the latest date when the system was running 
properly.
Click Next to continue.

3.  The system will start restoration. When all processes run to completion, the 

system displays a message informing you that the restore operation has 
completed successfully.

additional software, or otherwise modify system settings. To back up the system 
status, do the following:

→ All Programs → Maintenance → Backup and Restore.
