Microsoft SQL Server 2008 Express

Silent installer for Microsoft SQL Server 2008 SP3 Express. Information from http://msdn.microsoft.com/en-us/library/ms144259%28SQL.100%29.aspx#Accounts was useful and confusing in equal measure.

Caveat

Beware: SQL Server has lots of bits; this installer does not install everything nor remove everything. You may well need to tweak according to what you need to install. As it stands, it installs and removes just the basic SQL backend.
