No need to actually use Microsoft Update. Go google what chipset modem does your wireless card use. Then, go to the website of the chipset manufacturer to download the driver.

According to Google Search, Aztech WL552USB use rt2870 chipset. Correct me if I am wrong.

Ralink chipset driver for Windows can be downloaded at http://www.ralinktech.com/support.php?s=1

Aztech is so lazy to update the driver hosted on their site.
