Appearance and personalization
File Explorer
Networking
User accounts and security
File system
Other
- Start button was removed from the taskbar (although it was re-added in Windows 8.1). Replacement methods for invoking Start screen include a hotspot in the lower left corner of the screen, where the Start screen tile pops up, and a Start button among "the charms".
- "Recent documents" menu is removed from Start screen.
- Windows 8.1 no longer automatically adds newly installed programs to Start screen.
- Unified search is removed. A category-specific search replaces the former. It can search "Apps", "Settings", "Files" or within an app-specific index (such as, for example, e-mails from the Mail app) but not all at once. The default category is Apps, but can be changed before or after performing a search. Windows 8.1 restores this feature.
- Windows Desktop Gadgets, first introduced in Windows Vista, are removed.
Appearance and personalization
- The Aero Glass theme is replaced by a new theme with a flatter visual appearance in line with Metro design language. This is intended to prevent skeuomorphism. Aside from the taskbar, the new theme uses fewer transparency effects than the previous Glass theme.
- Flip 3D is removed. ⌘ Win+Tab ↹ now toggles between Windows Store apps and the desktop.
- The Windows Classic theme is removed. High-contrast themes (which previously used the Classic appearance) are modified to use visual styles.
- "Advanced appearance settings...", once found in Personalization\Window Color and Appearance part of Control Panel is removed.
- Sample pictures, sample music clips, sample video clip and preset user account pictures (a form of avatar) are no longer available.
- The sound schemes that were first included with Windows 7: Afternoon, Calligraphy, Characters, Cityscape, Delta, Festival, Garden, Heritage, Landscape, Quirky, Raga, Savanna and Sonata are all no longer available; only the folders remain in C:\Windows\Media, and they are empty.
File Explorer
- The Briefcase option under New context menu is removed by default, but can be reinstated by editing the registry.
- Windows 8.1 no longer shows Libraries by default.
- Chess Titans, Mahjong Titans, Purble Place, Minesweeper, FreeCell and Solitaire were removed. Updated versions of Mahjong, Minesweeper and Solitaire are available in Windows Store.
- Shortcuts to the Games Explorer were removed. The feature itself and its command line shortcut (shell:games) remain.
Networking
- For dial-up networking (DUN), some of the options under "Redialing options", such as "Redial attempts" and "Redial if line is dropped", are no longer available. Although dial-up networking using PSTN telephone line is becoming increasingly rare, this could affect users that still use it to connect to 2G, 3G and/or 3.5G mobile networks and also DSL subscribers that use the system's PPPoE dialer.
- The "Manage wireless networks" option on the task pane of the Network and Sharing Center control panel is no longer available, although a similar function is still available through the netsh command
- netsh wlan. Some of this functionality is reintroduced with the Windows 8.1 Update via the PC Settings app. Similarly, creating an ad hoc wireless connection via the "Set up a wireless ad hoc" option under "Set up a new connection or network" is no longer available through the GUI; users need to use the same netsh command or a third-party utility such as Connectify.
- One can no longer save a wifi connection to a flash drive from the Wireless Network Properties box under the Connection tab.
- Shortcuts for the Bluetooth File Transfer wizard, which are added by Windows 7 on a device with Bluetooth communication, are no longer provided. The utility itself (fsquirt.exe) remains available.
- Network Map is removed from Network and Sharing Center
User accounts and security

- Windows Defender:
- Can no longer schedule automatic system scans; it is now part of Windows Action Center's maintenance schedule

- Windows Media Center cannot run on startup or on top of other windows because of “new Windows OS requirements and behaviors”.
- Windows Media Player no longer has the Media Guide feature.
- DVD-Video and MPEG-2 Video codecs are no longer included. Video DVDs can be played in Windows Media Center.
- Windows 8.1 removes Facebook and Flickr support from the Photos app.
File system
- Backup and Restore is deprecated and renamed Windows 7 File Recovery in favor of File History.In Windows 8.1, only System Image Backup remains.
- Persistent shadow copies are no longer available. Therefore the ability to browse, search and/or recover older versions of files via the Previous Versions tab of the Properties dialog of files was removed for local volumes. Configuring and scheduling of previous versions of files was also removed from the System Protection tab of the Advanced System Properties (systempropertiesadvanced.exe) dialog box.
- CHKDSK utility only shows the progress percentage when running at startup.
Other
- Stop errors are simplified; specifically, several paragraphs of generic advice and auxiliary error codes are removed. Windows 8.1 added a Registry setting to revert the changes, which is also available to Windows 8 users after installing a hotfix.
- The sounds played upon login, logout and system shutdown were removed. The startup sound remains but is disabled by default.[citation needed]
