Around a third of NHS Trusts are still running Windows XP, seven months after support for the operating system officially ended.
The government paid Microsoft £5.5m in April to extend support for a year. This was meant to help Trusts begin their migrations. However, 35 percent of Trusts are still using XP, and some have no formal plans in place for an upgrade.
The information was uncovered by Citrix after making a Freedom of Information request.
Citrix identified 35 Trusts still using Windows XP, 74 percent of which are not planning to move away from the operating system until at least March next year.
This would give them a month to perform the upgrade, and raises the possibility that the NHS will have to pay Microsoft what is likely to be an even larger sum to extend support for another year.
Another 14 percent of Trusts have no current plans in place. Five percent are using XP through desktop virtualisation technology.
"Like the rest of the public sector, the NHS is under tremendous pressure to do more with less. The IT department is no exception," said Jason Tooley, UK country manager at Citrix.
"These findings highlight a wider opportunity for NHS Trusts across the UK to harness technology today to transform IT processes for the better.
"Using IT - including desktop and application virtualisation - can positively impact the entire workplace, delivering increased productivity and ultimately improved patient care."
V3 asked the NHS about its plans for upgrading from XP, and was told that individual Trusts are responsible for their own IT systems.
