AndySELECT windowid, content
FROM Table1 AS T

dateadded appears more than once in the table. Here's my stab at it:
DECLARE @.MyTable TABLE
(
WID int,
DateAdd datetime,
TableID int,
Content blah
)
--Generate the list of objects
INSERT INTO @.MyTable (WID)
SELECT DISTINCT t.windowid
FROM Table1 t
WHERE visible = 'True'
--fetch the target DateAdded
UPDATE @.MyTable
SET DateAdd =(
SELECT Max(t.DateAdded)
FROM Table1 t
WHERE visible = 'True'
and t.windowid = mt.WID
)
FROM @.MyTable mt
--fetch ID to break ties in DateAdded by an arbitrary rule (max)
UPDATE @.MyTable
SET TableID =(
SELECT Max(t.ID)
FROM Table1 t
WHERE visible = 'True'
and t.windowid = mt.WID
and t.DateAdded = mt.DateAdd
)
FROM @.MyTable mt
UPDATE @.MyTable
SET Content = (SELECT t.Content FROM Table1 t WHERE t.ID = mt.TableID)
FROM @.MyTable mt
SELECT WID as windowid, Content as content
FROM @.MyTable mt
