We are aware of this issue, At this stage Microsoft has issued patches for Windows 10 and a number of Server Products with other MS Operating Systems due soon.
A number of the patches have a requirement for Anti-Virus compatibility and we await feedback from Sophos on this and once resolved, we will deploy patches to our PC patch test rings via our usual delivery platforms. Once testing is completed, and if there are no showstoppers, we will then deploy to all Desktop systems.
We recommend that you frequently check your personal computers have the latest operating systems updates.
