Microsoft has stopped supporting and upgrading Windows XP as of April 8, 2014 and therefore any remaining customers running legacy XP systems will want to have a plan to get those systems upgraded or isolated.
Namely, migrate all your remaining computers off XP or - if you're running other legacy hardware or software that requires XP - make sure the old PCs are well firewalled off or, ideally, disconnected from your company network and the Internet altogether. Otherwise, without Microsoft system updates and security patches coming in, unsupported XP systems could threaten your data, computers and network, making the cost of upgrading pale in comparison to a major malware outbreak or other malicious attack on your company's infrastructure.
Still, says James Faw, stragglers still facing the XP choice today have probably resisted upgrading for one compelling reason or another. So, three Windows operating systems later, it may be useful to understand why a company waited till now, and how it can best get out of the XP bind.
Microsoft have run several webinars in the run up to the retirement of Windows XP. Click here to find out more.
