ECHO BackupScheduledTasks.bat,  Version 1.02

ECHO Backup and restore scheduled tasks in Task Scheduler's root folder

```
ECHO.
```

ECHO Usage:  Backup all: BACKUPSCHEDULEDTASKS

ECHO         Backup one: BACKUPSCHEDULEDTASKS /Backup "taskname"

ECHO         Restore:    BACKUPSCHEDULEDTASKS /Restore "xmlfiles" [ password ^| /Q ]

```
ECHO.
```

ECHO Where:  "taskname" is the name of the scheduled task to be backed up

ECHO         "xmlfiles" XML file^(s^) ^(wildcards allowed^) created by this batch

ECHO                    file's backup command or exported in Task Scheduler's GUI

ECHO         "password" is the password for the task's "runas" user

ECHO         /Q         restores the task, but without the "runas" user's password

ECHO                    ^(must be set manually afterwards^)

```
ECHO.
```

ECHO Notes:  Only tasks in the Task Scheduler's root folder will be backed up.

ECHO         Each scheduled task in the Task Scheduler's root folder is saved as an

ECHO         XML file in the current directory, with the task's name for file name.

ECHO         When restoring a scheduled task configured for a user other than the

ECHO         current user or SYSTEM, and neither /Q is specified nor a password

ECHO         provided, then you will be prompted for the "runas" user's password.

ECHO         Note that this password will NOT be masked while being entered.

```
ECHO         Tested in Windows 7 only.
