Microsoft Personal Web Server（PWS，个人Web服务器）是一个微软为Windows操作系统提供的个人Web服务器软件。PWS只被Microsoft在Windows 95、Windows 98、Windows 98 SE以及Windows NT 4.0中提供。它比Internet Information Services（IIS）的功能特性要少。

在Windows 2000之前，PWS是免费下载的，后来被一个Windows组件IIS所取代。Windows 98当中所包含的PWS4.0是它的最后一个版本，它也是Windows NT 4.0的可选安装包的一部分。注意，没有任何版本的PWS或IIS在Windows Me和Windows XP Home Edition中被支持，尽管IIS包含在任何其他Windows XP版本，而且PWS经验证可以被安装在Windows Me。

Microsoft Personal Web Server (PWS) is a scaled-down web server software for Windows operating systems. It has fewer features than Microsoft's Internet Information Services (IIS) and its functions have been superseded by IIS and Visual Studio. Microsoft officially supports PWS on Windows 95, Windows 98, Windows 98 SE, and Windows NT 4.0. Prior to the release of Windows 2000, PWS was available as a free download as well as included on the Windows distribution CDs. PWS 4.0 was the last version and it can be found on the Windows 98 CD and the Windows NT 4.0 Option Pack.
