Question to the Cabinet Office:

To ask the Minister for the Cabinet Office, what estimate he has made of the number of computers in the public sector that are using Windows 7; and whether his Department has set a deadline for the withdrawal of Windows 7 in advance of Microsofts' end of support for that operating system.

Decisions about technology choices rest with individual departments and bodies in the public sector. As such, Cabinet Office does not hold this information centrally.

The Cabinet Office itself does not have any computers using Windows 7.

The National Cyber Security Centre has published information on the upcoming removal of Windows 7 Support, here:
