Issues dropping distribution database

From time to time I came accross when using EM will not completely disable replication leaving distribution database. When you try to drop this database you will get the following error.
Cannot drop the distribution database 'distribution' because it is currently in use. The way to get around is to follow the following steps


USE master

GO
EXEC sp_configure 'allow updates', '1'
RECONFIGURE with override
GO
update master.dbo.sysdatabases
set category = 0
where dbid =

go
EXEC sp_configure 'allow updates', '0'
RECONFIGURE with override

GO
drop database
