@TrumanHW :
1. Have you tried both the drivers ? Both are good enough for your device.

(ii). By Sir canonkong ( PASSWORD : xiaofengmod )
2. Share your System information from the problematic Win 7 installation :
(i) Login as Admin.
(ii) Download & place this file on the desktop : SysInfo.bat : Google Drive Link
(iii) Make a new desktop folder with the name sysinfo
(iv) Run the SysInfo.bat file as Admin & let it complete.
(v) Now go into the sysinfo folder on the desktop & share the file.
Thanks & Regards. …
