Backup and Restore, the backup component of Windows that had been deprecated but was available in Windows 8 through a Control Panel applet called "Windows 7 File Recovery", is removed.
The update also removes the graphical user interface for the Windows System Assessment Tool, meaning that the Windows Experience Index is no longer displayed. The command line version of the tool remains available on the system.Microsoft reportedly removed the graphical Windows Experience Index in order to promote the idea that all kinds of hardware run Windows 8 equally well.
Windows 8.1 removes the ability of several Universal Windows Platform apps to act as "hubs" connecting similar services within a single interface:
The Photos app loses the ability to view photos from Facebook, Flickr or SkyDrive. Instead, each service provider is expected to create its own app;
The Messaging app, which was interoperable with Windows Live Messenger and Facebook Chat, is deprecated in favour of a Skype app that is not compatible with Facebook Chat;
The Calendar app can only connect to Microsoft services such as Outlook.com and Microsoft Exchange, with support for Google Calendar removed.
Beginning in October 2016, all future updates will become cumulative as with Windows 10; as such, downloading and installing updates that address individual problems would not be possible. Instead, upon installing Windows, users need only download a handful of updates as opposed to hundreds.
On April 8, 2014, Microsoft released the "Windows 8.1 Update", which included all past updates plus new features. It was unveiled by Microsoft vice president Joe Belfiore at Mobile World Congress on February 23, 2014, and detailed in full at Microsoft's Build conference on April 2. Belfiore noted that the update would lower the minimum system requirements for Windows, so it can be installed on devices with as little as 1 GB of RAM and 16 GB of storage. Unlike Windows 8.1 itself, this cumulative update is distributed through Windows Update, and must be installed in order to receive any further patches for Windows 8.1.
At the 2014 Build conference, during April, Microsoft's Terry Myerson unveiled further user interface changes for Windows 8.1, including the ability to run Metro-style apps inside desktop windows, and a revised Start menu, which creates a compromise between the Start menu design used by Windows 7 and the Start screen, by combining the application listing in the first column with a second that can be used to display app tiles. Myerson stated that these changes would occur in a future update, but did not elaborate further. Microsoft also unveiled a concept known as "Universal Windows apps", in which a Windows Runtime app can be ported to Windows Phone 8.1 and Xbox One while sharing a common codebase. While it does not entirely unify Windows' app ecosystem with that of Windows Phone, it will allow developers to synchronize data between versions of their app on each platform, and bundle access to Windows, Windows Phone, and Xbox One versions of an app in a single purchase.
Microsoft originally announced that users who did not install the update would not receive any other updates after May 13, 2014.However, meeting this deadline proved challenging: The ability to deploy Windows 8.1 Update through Windows Server Update Services (WSUS) was disabled shortly after its release following the discovery of a bug which affects the ability to use WSUS as a whole in certain server configurations. Microsoft later fixed the issue but users continued to report that the update may fail to install.Microsoft's attempt to fix the problem was ineffective, to the point that Microsoft pushed the support deadline further to June 30, 2014.On 16 May, Microsoft released additional updates to fix a problem of BSOD in the update.
