Windows 7 is very nice, then I install it on my Lenovo computer, I download it from Internet,so I donn't have a key,I use a small tool to activate it successfully ,several days ago ,the computer Automatically downloads some Updates from www.MicroSoft.com then I found that many Function cann't use any more,such as IIS. can somebody help me?

Hi, I would like to confirm where you downloaded Windows 7 from. This behavior may occur if it's not a Genuine Windows 7 system. Please confirm it first. Vivian Xing - MSFT

Hai,Some of the features like IIS mayn't be enabled by default. To check it go to Control panel > Programs > Windows Features on/off.Select if it lists there.regards from www.windowsadmin.infoManuPhilip
