Well it doesn't necessarely have to be a list of safe to delete items, in fact I would prefer a list that simply tells me what all the windows default scheduled tasks are doing.
For example some entries mention words like "SystemSoundsService", "FileHistory", "Windows Media Sharing", "Bluetooth".
So what I was thinking is that I always keep system sounds muted anway, I never used the file history, I don't use media sharing and I don't need bluetooth.
It just would be great to actually know what all these schaduled tasks do.
