Microsoft Windows Versions | CompTIA A+ 220-1002 | 1.2

In this video you will learn about various versions of Microsoft Windows and their features.

BitLocker

BitLocker is a full volume encryption feature included with Microsoft Windows versions starting with Windows Vista.  It is designed to protect data by providing encryption for entire volumes.  By default, it uses the AES encryption algorithm in cipher block chaining (CBC) with a 128-bit or 256-bit key.  A companion program called BitLocker To Go encrypts removable disks and USB drives.

Windows Media Center

Windows Media Center (WMC) is a discontinued digital video recorder and media player created by Microsoft that allowed for users to play videos, music & display slide shows, in addition to streaming media from sites like Netflix.  Media Center was first introduced to Windows in 2002 on Windows XP Media Center Edition (MCE).  It was included in Home Premium and Ultimate editions of Windows Vista, as well as all editions on Windows 7 except Starter and Home Basic.  It was also available on Windows 8 Pro and Windows 8.1 Pro as a paid add-on, before being discontinued in Windows 10, although it can reportedly be unofficially reinstalled using a series of command prompt commands.

BranchCache

BranchCache is a wide area network (WAN) bandwidth optimization software technology that is included in some editions of the Windows Server 2016 and Windows 10 operating systems, as well as in some editions of Windows Server 2012 R2, Windows 8.1, Windows Server 2012, Windows 8, Windows Server 2008 R2 and Windows 7.  BranchCache was designed to allow for efficient use of bandwidth for remote clients and offices.  To optimize WAN bandwidth when users access content on remote servers, BranchCache fetches content from your main office or hosted cloud content servers and caches the content at branch office locations, allowing client computers at branch offices to access the content locally rather than over the WAN.  In layman’s terms, BranchCache caches the most commonly requested data on a client computer so that bandwidth is not wasted on repetitive data requests.

Encrypting File System (EFS)

The Encrypting File System on Microsoft Windows is a feature introduced in version 3.0 of NTFS that provides filesystem-level encryption on all Windows systems.  The technology enables files to be individually encrypted to protect confidential data from attackers with physical access to the computer.
