I am using below schtasks command to schedule a task that runs every 5 hours. But it creates a task which ends after 3 days. I want to create a task which runs every 5hours infinitely: schtasks /create /RU "SYSTEM" /sc hourly /mo 5 /tn "My App" /tr C:\Windows\System32\calc.exe If I query the task it will below setting list(which says it end after 3days) using "SCHTASKS /Query" HostName: WINX22 TaskName: \VHDLdapBackupTask_testdays Next Run Time: 07-03-2012 07:00:00 Status: Ready Logon Mode: Interactive only Last Run Time: N/A Last Result: 1 Author: Administrator Task To Run: calc.exe Start In: N/A Comment: N/A Scheduled Task State: Enabled Idle Time: Disabled Power Management: Stop On Battery Mode, No Start On Batteries Run As User: WINX22\Administrator Delete Task If Not Rescheduled: Enabled Stop Task If Runs X Hours and X Mins: 72:00:00 Schedule: Scheduling data is not available in this format. Schedule Type: One Time Only, Hourly Start Time: 03:00:00 Start Date: 07-03-2012 End Date: N/A Days: N/A Months: N/A Repeat: Every: 4 Hour(s), 0 Minute(s) Repeat: Until: Time: None Repeat: Until: Duration: Disabled Repeat: Stop If Still Running: Disabled

The below command creates the task which runs infinitely. The property Stop Task If Runs X Hours and X Mins: 72:00:00 indicates that system will end the task if it runs continuously for more than 72hours(3days). schtasks /create /RU "SYSTEM" /sc hourly /mo 5 /tn "My App" /tr <application_path>

That statement is contradictory. Something won't run infinitely if it will be ended by the system after running continually for 3 days. From what I can see the only way to use schtasks to create a task that does not have this setting applied is to use the /xml option - create your task as you are now, or manually, turn off the setting in Task Scheduler, then grab a copy of the xml file from c:\windows\system32\tasks, then delete the task. Then you can use schtasks /create /tn {name} /xml {xml-file} Obviously if anything of the other properties need to be dynamic you'll have to create the xml programmatically, but at least now you have a template to use.

"runs infinitely" is not the clearest terminology. What T_M means is that it will be started every 5 hours from now on. It will only be terminated if a single execution tries to run longer than 72 hours.
