Windows Vista to Win 7 wont be lost. As its an upgrade.
U can choose to upgrade or do full clean installation.
Try control panel there, under Systems, is there an option to
let u upgrade or not.
If not, try downloading the starter pack or whatever ah
Only WinXP requires full clean installation.
The good news is that programmes still can function according to
specifications.
So I go and buy the software can liao? Ask the staff at com shop
can liao.
Data sure wont be lost right? U know how much It costs for the
software?
