According to the
Microsoft web site this email is a fraud and could "contain links to
malicious software or attempt to trick you into providing personal
information. Do not click any link in the message. Delete the message."
Click for Microsoft notice.
Operating Systems (Vista and XP) perform updates online in the
background while the computer user is at work or play on the computer.
We have never seen a case where Microsoft would send an email to users
regarding updates and revisions.
The best tip when
encountering any email that claims to have a software patch or critical
update is never click the links in the body of the emails and delete the
message to prevent infection. Most software companies
have support sections on their websites where users can check for real
updates and safely downloaded onto their systems.
