I upgraded the OS on my laptop from XP to Vista yesterday, it's not an upgrading actually, because I reinstalled the OS and did not migrate the settings and user data from XP.

 

All my data are stored on special partiton, driver C is only used by OS, so I format the driver c before I install Vista. the whole installation process took about forty mins, and another twenty mins for initial configuration.

 

My laptop is compatible with Vista, so it's very easy for me to install the OS, The only two drivers I need to install are power management and fingerprint reader. I also installed APS for protecting my HD.

 

The reason that I don't use Vista until yesterday is software compatibility, some software I need to use everyday can not be installed on Vista, and the stability of an OS without any service pack is my another concern. so I begun to use Vista from sp1.

 

I was struggling with the new OS all day long in yesterday. the most troublesome part is installing and configuring VPN client, I need to use Cisco VPN client and RSA soft token to connect to our enterprise network remotely, I encountered a lots of issues and connected to the VPN gateway finally.

 

It's a good mark, isn't it?
