Dear Mr Heath, Application under the Freedom of Information Act 2000 (FOIA)
Thank you for your request, which we received on the 5th May, for the information below: “How many computers are still running Windows XP?
When do you anticipate you will transition all of these XP machines to a new operating system?
Which operating system are you switching these machines to?
What parts of the department are these machines mainly used in?
How are you securing the XP machines in the interim period before their operating system is
Have you taken out an Extended Support deal with Microsoft to update these XP machines?
What is the cost of this Extended Support deal?
When does this Extended Support deal expire?”
All of this information is restricted by FOIA exemption s31 (1) (a) (prejudice to the prevention
or detection of crime). Section 31 is a qualified exemption which means if it applies I must
consider whether the public interest favours maintaining the exemption.
I accept the public interest in our procedures being transparent and generally understood.
This facilitates the proper public scrutiny of our processes and procedures which in turn
helps reinforce high standards of performance and governance.
On the other hand, disclosure of information that might assist those intent on committing
crime is not in the public interest. Anything that puts the running of HMRC at risk could
undermine confidence in the tax system and that would not be in the public interest.
It is in the public interest that HMRC is able to assess and collect tax as efficiently as
possible, at the least cost to the public purse and the minimum of additional burden to
taxpayers at large.
Information is available in large print, audio tape and Braille formats.
Type Talk service prefix number – 18001
So on balance, I conclude that the public interest favours maintaining the exemption.
