Windows 10 S is a specific configuration of Windows 10 Pro that offers a familiar, productive Windows experience that’s streamlined for security and performance. Windows 10 S will only run software that is vetted to be safe. It will provide enterprise grade protection from threats on the Internet and in the Cloud.
Macros automate frequently-used tasks; many are created with VBA and are written by software developers. However, some macros pose a potential security risk.
In order to help keep our users safe, Office on Windows 10 S is configured, by default, to block macros in documents received from the Internet. Some of those scenarios could include:
Documents downloaded from internet web sites or consumer storage providers (like OneDrive, Google Drive, or Dropbox)
Documents attached to emails that have been received from outside the organization (where the organization uses the Outlook client and Exchange servers for email)
Documents opened from public shares hosted on the internet (such as files downloaded from file-sharing sites)
How it works
Office uses the security zone information provided by Windows to determine if macros should be blocked. For example, if the location where a document originates from is considered the internet zone by Windows, then macros are disabled in the document, and the user is provided the following notification:
If you're sure the file is safe and want to enable macros
It's important to know that you don't have to enable macros in order to view or edit the document. However, if you want the macro functionality, you can unblock the file in question. To do this you will have to have saved the file you want to unblock to a local hard drive or OneDrive. Open Windows File Explorer and find the file that you want to unblock. Right-click the file and choose Properties from the context menu. At the bottom of the General tab you should see a section for Security. Select the Unblock checkbox.
The file should then be accessible from there normally.
