After installing Windows 7 Enterprise (x64) Operating System (OS) on the Dell Inspiron N4050 notebook [Intel Core i5-2430M (2.40 Ghz) CPU, 8 GB DDR3 1333 Mhz memory, 500 GB hardisk, etc], there are 5 unknown devices in the Control Panel -> System -> Device Manager as shown below:

  1. Ethernet Controller
    -> Installing the device drivers, Realtek Driver (RTL8105E-VB 10/100 Ethernet Controller) version 7.045.0516.2011, A01 (Network category) from Dell.

  2. Network Controller
    -> Installing the device drivers, Dell Driver R302627 (Wireless 1701 802.11 b/g/n, Wireless WLAN 1501 Half Mini-Card, Wireless WLAN 1503 Half Mini-Card) version 5.100.82.34, A00 (Network category) from Dell.

I have also installed the device drivers, Intel HD Graphics version 8.15.10.2342, A00 (Video category) from Dell because it is better than the Microsoft Standard VGA Graphics Adapter generic device drivers.

I have also updated the Dell Inspiron N4050 notebook BIOS from version A02 to A06. To improve the notebook performance, I have also installed the device drivers, Intel Rapid Storage Technology (R302547) version 10.1.2.1004, A00 (from Serial ATA category) from Dell.
