Businesses with PCs that have Windows 7 or Windows 8.1 installed can check out some improvements in today's cumulative updates for those operating systems. The changes are specifically for users of the Internet Explorer 11 browser.
In a blog post, Microsoft stated:
Effective today, the v.2 XML schema is now supported on Windows 7 and Windows 8.1, in addition to Windows 10. We encourage customers to migrate their existing site lists using v.1 to leverage v.2. Going forward, new features will only be brought to the v.2 XML schema. Customers should not consider moving to the v.2 XML schema until this patch lands on all of their devices.
The about:compat page in Microsoft Edge and Internet Explorer 11 helps customers manage their Enterprise Mode Site List by listing all of the compatibility features you or Microsoft have applied to sites on the client machine. Effective today, the about:compat page in Internet Explorer 11 is also available on Windows 7 and Windows 8.1, in addition to Windows 10.
