Del/f Create. bat parameter explanation:

Schtasks/create indicates creating a scheduled task.

/Tn specifies the name of the scheduled task

/Ru indicates the account that runs the batch processing. If this parameter is removed, the current account runs by default and a password is prompted.

The account used for a scheduled task will no longer run successfully if the password changes after the batch processing

Therefore, if I use the system Account system, the password will be omitted.

/Rp password of the specified account

/Tr specifies the path of the program, which is the path of the batch processing to be executed.

/SC is the specified running cycle

/D is the date. Here mon is the abbreviation of the English word, Monday
