Windows Update cannot check for updates because the service is not running.

I changed a hard disk in the Lenovo Service Center yesterday. By the way, they also helped me install the win7 64-bit system, because it contains a lot of domestic junk software (it is said that it is to facilitate those without computers ). There are exactly 360 security guards in it. I have never liked this. Generally, it is enough to install an MSE. So I simply deleted all these junk software. As a result, Windows Update will show this story later. Always Prompt:Windows Update cannot check for updates because the service is not running.

I found related information online:

A. disable the Windows Update Service in the service, delete all content in c: \ windows \ softwaredistribution \ datestore, and enable the Windows Update Service. (I tried it)

B. The answer from MS is as follows:

we can first try to manually start all services required for Windows Update. If it cannot be started manually, your services may be damaged. 1. Click the Start Menu, enter "services. msc" in the search box, and press Enter. If the User Account Control Window is displayed, click "continue ". 2. Double-click to open the "Windows Update" service.
3. Click the "General" tab to make sure that the "Startup Type" is "automatic" or "Manual ". Click "enable" under "service status.
4. Enable the "Background Intelligent Transfer Services", "Cryptographic Services", "Windows Installer", and "Software Protection" services in the same step.
5. What services cannot be started? What is the error? You can reply to us the name of the service that failed to start, or upload an error screenshot image as follows:
