Fixes an issue in which Task Scheduler runs a missed task even though the "Run task as soon as possible after a scheduled start is missed" option is not selected. This issue occurs on a computer that is running Windows 7 or Windows Server 2008 R2.
Here is how I use windows task scheduler: first run a command to create a task: c:\Windows\System32\schtasks.exe /Create /TN taskname /XML taskname.xml /RU username /RP password /IT after the task was created, in the general tab, "Run whether user is logged on or not" radio ...
What is launch failure in Task Scheduler? It’s an RDS server, so it reboots every morning. After it reboots, a warning message shows in history for the task “Task Scheduler did not launch task “Task” as it missed its schedule. Consider using the configuration option to start the ta...
