You can read about sp_MS_marksystemobject in Books Online.

 

If you want to see if all the procedures are going that route to disabel that you can use this command.

--Turn system object marking on
EXEC master.dbo.sp_MS_upd_sysobj_category 1
to stop that behavior run this command:
--Turn system object marking off
EXEC master.dbo.sp_MS_upd_sysobj_category 2

USE MASTER
GO
SELECT * FROM sys.objects WHERE NAME LIKE 'SP_%' AND sys.objects.is_ms_shipped = 0

SELECT * FROM sysobjects WHERE sysobjects.[name] LIKE 'SP_%' and category = 0
