However, if the required services cannot be stopped for any reason, or if required files are being used, this update will require a restart. If this behavior occurs, you receive a message that advises you to restart.
At the explicit request of the Dutch government, the release of this update on Windows Update will be delayed for the Netherlands.

Microsoft Security Advisory (2607712) – General Information

Microsoft is aware of active attacks using at least one fraudulent digital certificate issued by DigiNotar, a certification authority present in the Trusted Root Certification Authorities Store. A fraudulent certificate could be used to spoof content, perform phishing attacks, or perform man-in-the-middle attacks against all Web browser users including users of Internet Explorer. While this is not a vulnerability in a Microsoft product, this issue affects all supported releases of Microsoft Windows.

Microsoft is continuing to investigate this issue. Based on preliminary investigation, Microsoft is providing an update for all supported releases of Microsoft Windows that revokes the trust of the following DigiNotar root certificates by placing them into the Microsoft Untrusted Certificate Store:

DigiNotar Root CA
DigiNotar Root CA G2
DigiNotar PKIoverheid CA Overheid
DigiNotar PKIoverheid CA Organisatie – G2
DigiNotar PKIoverheid CA Overheid en Bedrijven

For supported releases of Microsoft Windows, typically no action is required of customers to install this update, because the majority of customers have automatic updating enabled and this update will be downloaded and installed automatically. For more information, including how to manually install this update, see the Suggested Actions section of this advisory.
