NEW YORK — Microsoft retires its 12-year-old Windows XP operating system on Tuesday. Even so, there are still millions of XP computers out there. Here's what to do if you own one of them:
What happens Tuesday?
Microsoft Corp. will issue its final update to fix known security flaws with XP.
After that, XP machines will still work, and you can install past security updates. You won't get new ones to address any new security flaws.
Your machine will face greater security risks. Because hackers know Microsoft will no longer issue updates, they have extra incentive to look for security flaws.
Microsoft will still provide updates for its anti-malware software for XP until July 2015, but the company warns it will offer limited protection.
Can I upgrade my computer?

If you can upgrade, you can buy a DVD version of the latest Windows 8 version for $120: http://bit.ly/1mQBzCe
You'll need to back up your files and have discs for old programs handy, as an upgrade requires wiping out your hard drive. Microsoft has a step-by-step tutorial: http://bit.ly/1mYSYEj
Keep in mind that it's likely better to use that $120 toward a new computer. You'll be getting something more powerful.
What if I keep using my XP computer, despite the risks?
Be sure to run all the previously released updates, plus the last one out on Tuesday.
If you don't need the Internet connection, unplug it. That will minimize the risk. Be careful about attaching USB storage drives, as that might introduce malicious software.
If you need the Internet, refrain from using email, Facebook and other communications channels through which malicious software might travel.
It's also a good idea to lock down your computer by using a profile that lacks administrative rights and to remove older software you no longer need.
