New Zealand businesses and consumers with PCs still running old Windows XP software have less than six months to upgrade their operating system, before the likelihood of their PC getting a virus or some other outside attack significantly increases.\nMicrosoft will end support for the XP operating system on 8 April 2014. From that date onwards there will be no further security updates or patches released, no number to call for technical assistance, and no online technical content updates from Microsoft. Essentially, XP users in New Zealand and around the world will be on their own, says Microsoft New Zealand in a press statement.\n\u201cWe estimate that up to 377,000 PCs in New Zealand running Windows XP could be vulnerable to malware attacks after 8 April 2014 and we want to make sure that Kiwis upgrade before Microsoft stops supporting Windows XP,\u201d says Dean Edwards, Windows business group manager, Microsoft NZ.\nMuch like other technology such as your mobile phone or digital camera, after 13 years XP is outdated. It can no longer handle people\u2019s expectations around data privacy and productivity, or the types of sophisticated cyber-attacks that now exist, says Microsoft.\nThe security risks for New Zealanders using XP will significantly increase, and both businesses and personal computers running XP will be impacted.\nMicrosoft says in New Zealand, around 18.8 percent of all personal PCs and over a quarter (25.3 percent) of PCs used by all types of businesses run on Windows XP.\n\u201cWe\u2019re well and truly at the stage where businesses and personal computer users need to upgrade to Windows 7 or Windows 8 \u2013 both to protect against risk, and to get the benefits of running a modern operating system,\u201d says Edwards.\n\u201cFor businesses, upgrading an operating system takes time. Depending on complexity, small businesses could take three to six months to upgrade, and larger businesses can take six months or more. We are really worried that some New Zealand companies are cutting it too close to the end of support date,\u201d says Edwards.\nBeyond security implications, hardware support for Windows XP and the availability of hardware drivers will continue to diminish, making the operating system progressively more difficult and costly to support. In addition to this, an increasingly long list of modern software, such as Adobe Photoshop and Microsoft Office 2013, cannot be installed on Windows XP.\nMicrosoft says a local organisation that has recently upgraded from Windows XP is House of Travel, which is number 83 in CIO100, the list of top ICT using organisations in New Zealand.\n\u201cWe had 1,100 computers running XP in all our offices and branches, and migrating them to Windows 8 caused little disruption to the business,\u201d says Dave Veronese, House of Travel CIO.\n\u201cIt was something we delayed doing for so long, but we\u2019ve already noticed the benefit of using more up to date software and would highly recommend upgrading for the advantages of the new operating system.\u201d\nAnalyst firm Gartner estimates more than 15 percent of midsize and large enterprises will still have Windows XP running on at least 10 percent of their PCs after Microsoft support ends next year.\nGartner analysts Michael Silver and Steve Kleynhans have listed three recommendations for organisations to ensure they will either be off these products or have considered the risks of continuing to run them.\nUnderstand the risks involved\nNot having support means PCs could be vulnerable to attack. New vulnerabilities are always being found, and new vulnerabilities that are found in more current products could affect Windows XP and Office 2003. Any unpatched device can be vulnerable to attack. Even if a device is only a private network and has no internet access, another device, even one running a supported product, can be infected with malware outside the private network and can bring it onto the private network, infecting other devices.\nMany applications will no longer be supported while running on Windows XP. Organisations may be on their own to resolve issues and problems, which could result in system downtime.\nAssess position\nOrganisations that are not almost or completely finished migrating off Windows XP and\/or Office 2003 should review their project plans and ensure they are on target to meet the deadline. Those that believe they're unlikely to complete their migration projects by April 2014 should prioritise their applications and users and reduce the risks by addressing critical resources first.\nClassify applications and users \u2014 work on critical ones first\nMost organisations have far too many applications. Organisations where users are administrators typically have one application for every 10 users, with about half of these requiring Windows to run. Gartner defines a critical application (or the user of critical applications) as one where if the application fails or the user can't do his or her job, there could be financial or legal consequences.\nOrganisations must conduct several analyses on their application portfolios to help safeguard the organisation after XP support ends, and in preparation for Windows 7 or 8 migrations.\nFollow CIO New Zealand on Twitter:@cio_nz\nSign up for CIO newsletters for your regular updates on CIO news, views and events.\nJoin us on Facebook.
