用于共享托管的asp.net webform应用程序的windows调度器替代

Hai guys,
Is there any alternative for windows scheduler for an asp.net application... The alernative must be capable of doing scheduled tasks as i am into shared hosting where i cant add any task scheduler to my server... I know there is quartz.net but my application needs only one task to be scheduled daily so i dont want to use it.... Any other alternative which can carry out scheduled tasks for me.... Is there any alternative for windows
