Extract OEM information from Lenovo win7 oem CD;
.
Lenovo's OEM information is in boot.wim in the sources folder. You can extract the boot.wim with UltraISO, and then open it with the Chinese version of Gemeix 2.0.17 (I used 7Z). There will be three folders and one file, and the OEM information is in the folder named "2" by Lenovo!
