Automated System Recovery is a new feature in Windows XP that adds another way to perform a system recovery should things go bad. Use ASR as a last resort in system recovery, only after you have exhausted other options such as the startup options Safe Mode and Last Known Good Configuration.
How to Set up and Use Automated System Recovery in Windows XP
Notes:
1. ASR does not include data files. Back up data files separately on a regular basis and restore them after the system is working.
2. Using All information on this computer in the simple wizard also creates an ASR floppy disk and an ASR set.
3. ASR supports FAT16 volumes up to 2.1 GB only. ASR does not support 4 GB FAT16 partitions that use a cluster size of 64K. If your system contains 4-GB FAT16 partitions, convert them from FAT16 to NTFS before using ASR.
