Spell checker was removed by MS in 2010 due to language pack issues.
Is it available in 2012?
If not, can an IE browser add-in be used for System Centre?
The status, as of right now is the same in 2012.
See Patrik's answer here:
Since SCSM console uses WPF the IE browser add-in does not apply. You can find more information out on IESpell here: http://www.iespell.com/
