In practice, this means installing Windows security patches as soon as your corporate information security policy allows and subject to appropriate testing. This advice fits within AP ENPS’s traditional guidance to our customers about installing Windows patches.
We continue to test AP ENPS functionality both with and without the Spectre and Meltdown patches and we do not anticipate any negative impact from installation of the patches. If you have a specific question, please contact the AP ENPS team at firstname.lastname@example.org or on our 24-hour support hotline.
