What if the task Scheduler in the Win7 system doesn't open?

We are likely to encounter this situation when we use the computer win7 Pure edition. Suddenly want to use a program but there is no use of the situation, today I encountered this situation, when I opened the task Scheduler prompted me to say "The Task Scheduler service is not available ..." Then I began to see why.

The first step is to go into the admin tool, find the Task Scheduler, and then open it and see that there are a lot of options on the main page, and then I click on the first folder under the program and it's easy to look at the picture.

And then came out of the subfolder of the page, there are a lot of features, and then I saw my computer service is not turned on, is disabled, and then I will be the service program features open, and then the last step left.

Then return to the page to open the operation of the program, the result is that this causes my computer can not open the function of the scheduled task, we encountered such a situation may wish to try their own, perhaps just do not know when not open on the cause of the program is not available, Sometimes it's a simple little way to solve the big problem we think.
