After 12 years, Windows XP officially becomes an unsupported OS. Here's what you need to know, from old PCs to dicey ATMs.
Windows XP Game Over: 9 Upgrade Options
(Click image for larger view and slideshow.)
Windows XP has been around for more than 12 years and has hundreds of millions of users. But the operating system receives its last Patch Tuesday updates this week. A relatively light bundle of four fixes, the patches unceremoniously retire the still-popular OS, which, as of last month, had more than twice as many users as Microsoft's newest flagships, Windows 8 and 8.1
A few banks, governments, and other large-scale XP customers will still get support from Microsoft, albeit for millions of dollars each. Until 2015, Microsoft will additionally supply antimalware definitions to those who have its Security Essential software installed. Many antivirus companies will also provide support for at least the next couple years.
But without official security patches, updated antimalware signatures might not keep XP users safe, especially if, as some have speculated, cybercriminals have stockpiled zero-day attacks in anticipation of this week's deadline. To some, every XP user represents a potential Pandora's Box of botnets, malware proliferation, and even hacked ATMs. But to others, such worst-case predictions represent the biggest hyperbole this side of Y2K.
Which side has it right? Here's what you need to know to about XP's end-of-service deadline.
1. Is the risk real? Yes, though it depends how the PC is used. Windows XP is already more malware-prone than newer systems, and it will only grow more vulnerable now that Microsoft has dropped support. That said, savvy users who can't or don't want to upgrade have a number of options to make their systems more secure, including disconnecting it from the public Internet, employing firewalls, and removing programs and plug-ins that are known to be risky.
2. Why is Microsoft abandoning such a popular product? To be fair, Microsoft has supported Windows XP for a long time. The company boasts "one of the broadest and most transparent support policies out there," Gartner analyst Michael Silver told us in an interview last month. "You're not going to get that from other vendors."
Moreover, Windows XP was built for a different era of computing, a point Microsoft sometimes makes when explaining the OS's security risks. For more than a decade, the company has dedicated resources to XP triage, and it probably wants to use those resources for others projects -- you know, the kinds that actually generate new revenue.
That brings up the more cynical side of XP's retirement. The OS's licensing worth has run its course, and XP isn't an ideal platform for the cloud-based apps and services around which the company is now hedging its bets. Windows XP might be popular, in other words, but it doesn't represent the same revenue growth that newer systems do. Some have argued that Microsoft could turn XP into a revenue source by making extended support widely available as a subscription service, but the company has shown no interest in such tactics.
It helped that Windows Vista, XP's follow-up, was dismissed as bloated and buggy. Without a compelling need to upgrade, many users stuck with Windows XP longer than normal, allowing it to build up an enormous user base that's been slow to erode.
For many people, XP remains adequate. Not everyone needs the fastest processors or all the newest bells and whistles, and for this crowd, XP has been reliable enough to keep around.
Others would happily upgrade but cannot afford to do so, though the research firm IDC last year said companies would end up paying three times more if they delayed upgrades. Others still need XP for old applications that won't run correctly, or at all, on new platforms.
4. Do I need to worry about using an ATM? Probably not, but there is some risk. As of earlier this year, around 95% of ATMs reportedly ran on Windows XP, and many of them haven't been upgraded yet. That's unsettling, but not all of them pose equal risk.
Large banks obviously have the most financial flexibility to update their machines and have been doing so over the last several months, though the job is ongoing. Many of them are also paying Microsoft for extended support, no doubt mindful of the PR fiasco that will ensue if hackers find a way to steal customers' cash.
Moreover, not all XP-based ATMs are vulnerable in the first place. Some run a version of XP that will lose support this week, but others run a version of Windows XP Embedded that Microsoft will continue to support for the next several years. Unfortunately, ATMs that run the retired version can be indistinguishable from those running the supported one.
The risks are likely to be highest among older units, many of which cannot receive software upgrades and will need to be replaced wholesale. Given that new units can cost tens of thousands of dollars, it's not clear how quickly these replacements will occur. So while bank customers probably won't be affected, you might want to think twice before inserting your debit card in an ancient-looking ATM crammed in the corner of a liquor store.
5. I'm still running XP -- am I doomed? Don't worry. Unless you're particularly unlucky, and likely also a little careless with email attachments or suspicious links, no one is going to steal your identity or hijack your computer before you finish reading this article. But every day, the risk will get greater.
As mentioned, tech-savvy users are employing a variety of tactics to stick with XP. Some have moved their XP-based PCs to private networks or offline use, which should eliminate almost all threats. Others have disabled Java and Adobe Flash and switched from Internet Explorer to Chrome, strategies that should mitigate but not necessarily eliminate dangers.
Silver, the Gartner analyst, compared continued XP usage to driving an old car: With enough work, it will keep running. But one day, you might find yourself stranded.
But if you don't want XP's risks and aren't interested in frequent security maintenance, you still have a variety of options. Microsoft hopes many XP users will buy new Windows 8.1 machines, which, thanks to this week's update, will be more familiar to non-touch users. But XP systems can also be repurposed for Linux or upgraded to Windows 7 with an OEM license. Relatively new XP machines might also run the updated Windows 8.1, though Microsoft reps have assiduously avoided any promises in this regard. Other options include switching to a tablet, Mac, or Chromebook.
