We have deployed Microsoft Windows 7 (32-bit) in ITSC User Area at 1/F Pi Chiu Building this summer.
Windows XP is still provided in training rooms* as an alternative. Most of the software are similar in both Windows but Microsoft Office 2010 is only available in Windows 7.
As usual, you can select Chinese or English version in both Windows 7 and XP as your working environment.

*ITSC Training Room 1 (Rm 102) provides Windows XP only.
