INTRODUCTION The Windows 7 login script I inherited
Displays a login screenPerforms account authenticationChecks for blank usernames and
passwords less than 8 charactersAuto login capability does not work. Auto login implemented using
threading.

FLOW CHART
REQUIREMENTS: AUTO SHUTDOWN Shutdown the computer at any
scheduled time
REQUIREMENTS: AUTO LOGIN Create a 2 GB H: drive partition Run login.vbs Run LibraryDefaultPage.vbs Display desktop
UNIX TIMESTAMPS Number of seconds since 12 a.m. Jan. 1,
1970 E.g. 5/3/2013 5:54:17 PM 1362518657.85
DESIGN: AUTO SHUTDOWN Problem 1: time is not a Unix timestamp ['11:20', ''] 1362063000.0
DESIGN: AUTO SHUTDOWN Solution: Step 1: Get the month, day, year
now
datetime.datetime.now()
month
day
year
str(now.month)
str(now.day)
str(now.year)
DESIGN: AUTO SHUTDOWN Step 2: Get the hour, minute, second hour,minute =
shutdownTimeList[0].split(‘:’) 11:20
hour = 11minute = 20
second = “00”
DESIGN: AUTO SHUTDOWN Step 3: Make a date string
e.g. mm/dd/YYYY HH:MM:SS Step 4: Make a timestamp Time.mktime.datetime.datetime.strptim
e(date_string, “%m/%d/%Y %H:%M:%S”)
e.g. 1362063000.0
DESIGN: AUTO LOGIN Threading abandoned Therefore:
shutdown –a: cancels shutdown/restart shutdown –r –t xxx: sets restart for xxx seconds
['1358517600000', '1358523000000', '1358527500000', '']
DESIGN: AUTO LOGINnow

restart 60 sec. afterauto login period
time.time()
os.system(“shutdown –r –t xxx”)
• clear any restart/shutdown• create 2 GB partition for H: • call login.vbs with
auto login credentials• call LibraryDefaultPage.vbs
DESIGN: AUTO LOGINnow restart 60 sec. after
auto login period
• clear any restart/shutdown• create 2 GB partition for H: • call login.vbs with
auto login credentials• call LibraryDefaultPage.vbs
os.system(“shutdown –a”)
subprocess.call(“diskpart /s command.txt”)shell.Run(“wscript.exe [file path]”)
DESIGN: AUTO LOGIN Problem: Multiple auto login times
Auto Login Start TimeAuto Login PeriodAuto Login End TimeOutside Auto Login Period
now
DESIGN: AUTO LOGIN Solution: Boolean flag
Auto Login Start TimeAuto Login PeriodAuto Login End TimeOutside Auto Login Period
now
flag
DESIGN: AUTO LOGIN Problem: auto login after auto shutdown
Auto Login Start TimeAuto Login PeriodAuto Login End TimeOutside Auto Login Period
now auto shutdown
flag
DESIGN: AUTO LOGIN Solution: global variable
autoShutdowntime
Auto Login Start TimeAuto Login PeriodAuto Login End TimeOutside Auto Login Period

IMPLEMENTATION hour, minute =
shutdownTimes[0].split(':') dateString = month + "/" + day + "/" +
year + " " + hour + ":" + minute + ":" + second
time.mktime(datetime.datetime.strptime(dateString, "%m/%d/%Y %H:%M:%S").timetuple())
