Question to the Department of Health and Social Care:

To ask the Secretary of State for Health and Social Care, whether he has made an estimate of the number of computers in the NHS that use the (a) Windows XP and (b) Windows 7.

The NHS England Cyber Security Operations Centre (CSOC) monitors over 2 million devices across the NHS IT estate, identifying and preventing cyber threats. This includes monitoring the number of National Health Service computers using Windows XP and Windows 7, which stands at approximately 0.58% of the visible NHS estate.

The Department works with NHS England to monitor levels of unsupported systems across the NHS estate and to ensure that the risks are being appropriately managed. This includes taking regulatory action where organisations are not doing so. Where organisations are still running operating systems such as Windows 7 or Windows XP, such as on some large, legacy clinical devices, they are required to implement additional controls to manage the cyber security risk.
