Dealing with win7 can not automatically update the problem has a coup

  
If the user installs a genuine Windows7 system, the system itself automatically opens the Windows Update automatic update function. However, some users use pirated Win7, this security feature is often turned off. However, after entering the win7 system today, I want to update the system. Who knows that after clicking "automatic update", it appears: windows update cannot check the update at present, because the service is not running, you may need to restart the computer. Why is this suggestion? How to solve it?
Depressed! First check the update service:
Computer--Management--Service--windows update
Found that it is already Start " Status.
So clicked on "restart" to restart the service, but still did not solve the problem.
Found a solution:
Open a command prompt window as an administrator and run the following command:
net stop WuAuServ
cd %windir%
ren SoftwareDistribution SDold
net start WuAuServ
Do not restart, click Windows Update, OK!
The reason why this problem occurs, I guess it should be a few days ago to clean the C drive, accidentally deleted the SoftwareDistribution folder file. With this in mind, the whole person has a sweaty word.
