Upgrading Hyper-v to the final release wasn't as smooth as I thought it would be.

I was a little surprise that the upgrade wasn't as seamless. I followed the instruction from http://support.microsoft.com/kb/950050, but still had issues. After the upgrade, I couldn't start any of my VMs. I had to delete and create new ones. Then my network adapter was removed, so I had to create a new network adapter. My VM finally came up, but the mouse didn't work, so I had to install the new integration services. I just finished that. My system is rebooting, so I'll see what other problems I'll run into.
