Windows 7 woes...

I've been hearing a lot of good things about the Windows 7 Release Candidate, not too may people are saying much bad about it. I admit, I do like it better than Vista, but there are a few stumbling blocks I have run into...
First, The upgrade from Windows 7 Beta to Windows 7 RC has been blocked!

I went around this limitation and followed the directions here: http://www.blogsdna.com/3083/how-to-upgrade-windows-7-beta-build-7000-to-windows-7-rc-build-7100.htm

and upgraded to build 7100. great! First issue, no Start Menu. Not a true problem for me, most of my programs are either pinned to my Toolbar or I fire them off from the Run command.

Second problem, No Internet Access. This took a bit more troubleshooting, after a Reboot, sometimes the computer would add 0.0.0.0 as the default gateway ALONG with my true Default gateway.

again, another easy fix if you know how:
Start a Command prompt Window as an elevated administrator (If you run as a standard user, this won't work)
Type
ipconfig

in your default gateway, you should see 0.0.0.0 along with your normal gateway. If you do! Great!
Type Route Delete 0.0.0.0
then type
ipconfig /renew

and voila! Your Default Gateway is working again, and you can hit the Internet!
