Microsoft has already pulled the plug on support services for MOSS 2007. Come 2020, a similar fate awaits SharePoint 2010, while SharePoint 2013 users will lose support privileges just three more years later. Considering all these factors, it’s probably a smart idea to switch to the latest avatar of the collaboration platform, SharePoint 2016, anyway.
Users accidentally deleting documents, versions of documents, folders, list items, document libraries, or lists from SharePoint farms are some of the nightmares many administrators have to deal with. If this happens with regular Windows Explorer, then users pressing Shift + Del delete the item irrecoverably.
