Who can be affected?
1) Customers running Windows 10 are not affected.
2) In March 2017, Microsoft had released a security update. Those who have Windows Update are protected. If not , we suggest you immediately deploy the patch Microsoft Security Bulletin MS17-010 .
3) Customers who are running supported versions of the operating system (Windows Vista, Windows Server 2008, Windows 7, Windows Server 2008 R2, Windows 8.1, Windows Server 2012, Windows 10, Windows Server 2012 R2, Windows Server 2016) will have received the security update MS17-010 in March. If customers have automatic updates enabled or have installed the update, they are protected. For other customers, we encourage them to install the update as soon as possible.
4) Unsupported systems running Windows XP, Windows Server 2003 did not get any Security Update in March 2017. So, there is every likelihood of the systems getting affected. While Microsoft has a Public Policy of not supporting very old systems, it has however made an exception this time and released Security Patch even for unsupported OS.

Recommended plan of action:
1) For Windows 10 users, your systems are protected as long as you apply patches. We recommend you enable MAPS in Windows Defender.
2) For supported Operating Systems, please apply the patch if not applied so far.
3) If you are a user of EMS , then your systems are safe as EMS ensures that systems are patched . Customers not using EMS can consider using EMS.
4) If you are using Office 365 , there are 2 things to be done. One is that you store all your files in One Drive or SharePoint .
