Answer 1

Its one of the DLL files for HTTP services.

Answer 2

Recommendation for winhttp.dll: is to get control over your running programs.

Purpose

Microsoft Windows HTTP Services (WinHTTP) provides developers with an HTTP client application programming interface (API) to send requests through the HTTP protocol to other HTTP servers.

Where Applicable

WinHTTP supports desktop client applications, Windows services, and Windows server-based applications.

WinHTTP is not recommended for applications built on the Microsoft .NET Framework, because .NET Framework applications should use the networking facilities in the System.net classes.

Important With WinHTTP version 5.1, the WinHTTP 5.0 download is not available. As of October 1, 2004, Microsoft has removed the WinHTTP 5.0 SDK download from MSDN and terminated product support for version 5.0.
