Windows Update is currently unable to check for updated solutions

"Windows Update is currently unable to check for updates because the service is not running. You may need to restart your computer. "This is the error that was encountered when I used Windows Update to check for updates when I backed up a good windows 7 a year ago. From the error hint we seem to be able to solve this annoying problem from two places: first, restart the computer and try again, the result is invalid! Second, open the Windows Update Service in Services.msc, but when I try to do this, I find that the service is open. What to do?

A truly effective solution:

1. Enter CMD in the Start menu search box and enter net stop WuAuServ in the command prompt at open;

2, in the Resource Manager Address bar input%windir%, enter, find the name "SoftwareDistribution" folder, and renamed it "Sdold";

3, enter the net start WuAuserv in the command prompt opened at the first step;

Try Windows Update again, success!

Program Interpretation:

The first step of the net stop WuAuServ command in the

solution is to stop the Windows Update Service in order to rename the "SoftwareDistribution" folder to open windows again after it has been successfully renamed The update service is successful. It also means that the key to the problem is softwaredistribution this folder! The role of SoftwareDistribution is to record Windows Update and write the appropriate upgrade information to the registry. Of course, if an error is encountered during the upgrade, the registry is written accordingly, and whenever Windows Update, the system first accesses the SoftwareDistribution folder, so if the error records in this folder, Windows Update will not function properly, when we rename or delete it. A new softwaredistribution is rebuilt when Windows update, so the upgrade can continue!
