there seems to be a slight "controversy" brewing here, about whether one needs to UNdo the Microsoft work-around ( FixIt 50486
Calendar of Updates is advising people that "you do not need to undo the work-around" (i.e., "you do not need to use FixIt solution 50487
to disable the work-around"). http://www.calendarofupdates.com/updates/index.php?app=calendar&module=calendar&cal_id=&do=showevent&event_id=76441
However, Microsoft itself indicates that they are leaving the "Fix-It" on line "so that [users] can undo the Fix It after you install the security update". http://support.microsoft.com/kb/2286198 If Microsoft suggests the plausibility/necessity of undoing the FixIt after
installing the security update, it seems to me all the more reasonable for one to remove it [even] before
installing the security update.
The bottom line: even if today's Security Update automatically undoes the FixIt --- which I don't believe it does --- it couldn't hurt anything to manually undo the FixIt first.
As for people who used an alternative
FixIt tool, such as the one by SOFOS, I would certainly advocate that this be undone PRIOR to applying the Microsoft Update.
