The task scheduler service is disabled on my vista os as well. I've looked everywhere for a way to re-enable without any luck.
I was attempting to backup my files in Vista when I got an error message stating that the Task Scheduler Service is not running.I went into Services and found the Scheduler was disabled. When I right-clicked that service all the start-up options were grayed-out. I checked out the dependencies and they were all running.
I logged-on as Administrator and that didn't work.
Does anyone know how to enable the Scheduler?
