Win7 system task scheduler can not open how to do

We are likely to encounter such a situation when using the computer win7 pure version, suddenly want to use a program but there is a situation that is not available, today I encountered this In the case, when I opened the task scheduler, I was prompted to say "The Task Scheduler service is not available..." and then I started looking at the reason.
The first step is to enter the management tool, then find the task scheduler, then open it, see that there are many options in the main page, then I click on the first folder under the program, look at the picture It is very simple to do. Page

then came out of subfolders, which will have a lot of features, and then I saw my computer service is not turned on, is disabled, and then I put the function service program open, then The last step is left.

then return to pages that are open operation, the result is this causes my computer does not turn on the normal function of the mission plan, we might have a situation where they can try, perhaps do not know when If it is not open, the program will be unavailable. Sometimes it is a simple small method that can solve the big problem we think.
