# regback.pl
#   Plugin to assist to determine if a registry backup was executed and
#   provide the key name of the log file which is located at
#   Windows/System32/logfiles/Scm/.
#   It will then go out and list all tasks scheduled through the 
#   task scheduler along with the name of each log file associated 
#   with that task.  It will then print out the last written time and date.
#   This is for Windows NT systems ONLY (Vista, Win 7, 2008) blog post
