San Francisco, Aug 3: Microsoft had faced a critical Windows bug that had allowed attackers to gain control of infected machines via program shortcuts.
Microsoft had emerged an emergency patch over the issue on Monday, Aug 2.
Microsoft usually issues patches to fix software flaws just once a month.
But the seriousness of the bug forced the software giant to issue an emergency patch outside the normal schedule.
However, computers still running Windows XP Service Pack 2 or Windows 2000 were not included in Monday's (Aug 2) fix, because Microsoft, as previously announced, has stopped supporting those operating systems.
