Use System Restore.
Even if SR claims that there are no images available to restore from, they can still be there.
AT.Exe 17:45 /interactive "C:\Program Files\freeCommander2005\freeCommander.Exe"
SchTasks.Exe /Run /TN "AT1"
Navigate to "C:\System Volume Information" directory and search for the appropriate files. If they're still there, harvest them. Backup your current registry using a program called "ERUNT". From a different XP installation, locate and replace the SYSTEM, SOFTWARE and NTUSER.DAT files with the ones from the SVI directory.
The FreeCommander2005 and ERUNT programs can be found under the Freeware section of
WWW.SnapFiles.Com .
