WMI Learning
After two days of study, we found that WMI is indeed a good thing. using it, we can easily manage computer hardware information, but the hardware information obtained with it is very limited, it is especially suitable for users who do not have high requirements on hardware information details. For example, some OEM vendors manage and detect online products, from then on, I have said Byebye to those tedious Apis ......

The following are some examples of my learning experience over the past two days:
