  • If you perform an in-place upgrade of Windows XP, all existing  restore points are removed and a new System Checkpoint restore  point is created after the in-place upgrade is complete. Do not  perform an in-place upgrade if you may need to use System Restore  to roll your system back to a previous state.For additional  information, click the article number below to view the article in  the Microsoft Knowledge Base:

  • Backup copies of your registry files (in the  %systemroot%\Repair folder) are also replaced after the in-place  upgrade is complete. The registry files in the Repair folder are  either from the first time you started Windows XP or the last time  you used the Backup utility to backup your System State. Copy  these registry backups to another location before you perform an  in-place upgrade if you may need to use them after the in-place  upgrade is complete.
