Computer software giant Microsoft declared an emergency patch recently, regarding an important Windows bug which needed correction immediately. The in - emergency Windows bug had started allowing PC attackers to be in control of the infected machines through program shortcuts.

Usually, it is Microsoft which issues patches in its attempt to try and fix its software flaws and errors only once in a month. However, the seriousness of the situation made the priority of the emergency higher and forced Microsoft to issue an emergency patch beyond its usual familiar schedule.

The flaw was broadly publicized last month as it was made use of to attack the industrial control systems in the manufacturing and utility control systems through a virus called the Stuxnet worm.

The way in which Windows creates shortcuts of various programs, files, applications and software which are frequently used has been exploited, and the flaw was made use of to execute on its own malware that gives control of the computer over to attackers.

However, since Microsoft has ceased to support the operating systems Windows XP Service Pack 2 or Windows 2000, computers still running on them were not included in the flaw-fix.
