When Microsoft launched on May 12, 2010, it marked a seismic shift in how organizations approached intranets, document management, and team collaboration. Arriving five years after the controversial SharePoint 2007 (MOSS) and riding the wave of Windows Server 2008 R2 and SQL Server 2008, SharePoint 2010 was not merely an upgrade—it was a re-architecting of the enterprise content management (ECM) landscape.

Microsoft heavily promoted Silverlight 4 as the rich client for SharePoint 2010. Drag-and-drop document upload , calendar overlays , and chart web parts all required Silverlight. As we know, Silverlight died by 2015, leaving many 2010 customizations broken in modern browsers. Today, any surviving SharePoint 2010 farm will have disabled Silverlight or forced IE mode in Edge.

replaced the monolithic SSP, allowing services (e.g., Search, Managed Metadata, User Profiles) to be shared across web applications and farm instances.
