Utility to remove Beta 2 and previous CTPs

If you have previous Beta or CTP versions of SQL Server 2005 installed and you’d like to play with the September CTP, Microsoft provides an utility to cleanly remove the older version and .Net Framework. The utility is called sqlbuw.exe, located at CD-Rom\SQL Server x86\Tools\Setup Tools\Build Uninstall Wizard.

It worked great for me on both my laptop and desktop. On my laptop, I had Beta 2; on desktop, June CTP.
