Your notebook is produced by Wistron, which is a relatively large notebook OEM. Many notebook brands, such as Hewlett-Packard Fujitsu, ask Wistron for OEM production.

Now the notebook industry is buying computers instead of producing notebooks, which are made for foundries. Lenovo, Shenzhou Sony Apple are all like this.

Your HP computer is made by Wistron, so you tested the word Wistron with test software. This is normal.

Notebook foundries include Quanta Wistron Compal He Zhi and so on. These foundries only produce notebooks and do not sell them directly to end users. The customers of the foundry are notebook brand manufacturers such as Lenovo and Shenzhou Hewlett-Packard. Notebook OEM is also called OEM.
