Windows 8 is the successor to Windows 7 in Microsoft's Windows line of operating systems. Several features which were present in Windows 7 are no longer present in Windows 8.
Games such as Chess Titans have been removed. However some of them are now available on the Windows Store.
For dial-up connection (DUN), some of the options under Redialing options such as "Redial attempts" and "Redial if line is dropped" is no longer available. Although dial-up using PSTN telephone line is becoming increasingly rare, this could affect users that still use DUN to connect to 2G/3G/3.5G mobile network and also DSL subscribers that use Windows' PPPoE dialer.
The Manage wireless networks under Network and Sharing Center is no longer available, although a similar function is still available through netsh command (netsh wlan).
Similarly, creating an ad-hoc wireless connection ("Set up a new connection or network" > "Set up a wireless ad hoc") is no longer available through the GUI; users need to use the same netsh command or third-party utility such as Connectify.
Windows Media Center will no longer be included by default in any version of Windows 8, but is available as a free add-on for Windows 8 Pro until 31 January 2013.
Windows Media Player will no longer include codecs to play DVDs, but DVDs will be playable if the Windows Media Center add-on is installed.
Windows Media Center cannot run on start up or on top of other windows because of “new Windows OS requirements and behaviors”.
Windows DVD Maker has been removed.
The POSIX subsystem, SUA, has been deprecated and will be removed from the next release of Windows.
Backup and Restore has been renamed Windows 7 File Recovery in favor of the new feature called File History.
The Blue Screen of Death no longer shows as much technical information about the error that caused the computer to stop.
Windows CardSpace has been removed in favor of the new feature U-Prove.
The Parental Controls feature present in earlier versions of Windows has been removed and replaced by the Family Safety feature.
Chkdsk only shows a percentage when running at start up.
