Windows Server 2003, 2008, 2008 R2 and Windows XP, Vista and 7.

Warning Signs

There have been several signs that Microsoft has been trying to patch vulnerabilities. The 1st indication of the impending attacks was when MS provided a patch to the long-dormant Windows XP after many years without an update.

Several US governmental and private entities have issued very serious “Update NOW” notifications to the system administrators, although the initial fears of s “WannaCry-esc” worm lawlessly spreading have yet to rear its head but this is an issue to take seriously.
