| The first-generation Surface (launched as Surface with Windows RT,[2] later marketed as Surface RT)[3] is a hybrid tablet computer developed and manufactured by Microsoft. Announced on June 18, 2012, it was released on October 26, 2012, and was the first ever personal computer designed in-house by Microsoft.
 
 The Surface tablet has a display of 1366x768 pixels on a five-point multi-touch touchscreen with Gorilla Glass 2. The device measures 10.81 by 6.77 by 0.37 inches (27.46 cm × 17.20 cm × 0.94 cm) and is made from magnesium. The kickstand, USB port and a magnetic keyboard interface give the Surface ability to add a wireless mouse, external keyboard or a thumb drive. There is also a slot for a microSD card to add up to 200 GB.
 
 Surface runs Windows RT, which is preloaded with Windows Mail, Calendar, Contacts, Sports, News, Travel, Finance, Camera, Weather, Reader, SkyDrive, Store, Photos, Skype (no longer supported), Maps, Games, Messaging, Bing, Desktop, and Xbox Music and Xbox Video Windows Store applications, and supports Microsoft Office Home and Student 2013 RT, which includes Word, PowerPoint, Excel, and OneNote within the Desktop application. Windows RT only allows installing Windows Store applications. Windows RT is compiled entirely for the ARM instruction set architecture.
 
 A major update to Windows RT 8.0 was launched October 17, 2013, called Windows RT 8.1. This update brought many improvements to the Surface, such as an overhauled Mail app, more Bing apps like Reading List, and OneDrive (updated from SkyDrive). It also brought support for larger tiles, a help and tips app, Internet Explorer 11, Outlook 2013 RT, changes to PC Settings, lockscreen photo slideshow, infinitely re-sizable apps, a Start button, and speed improvements. Later, an update to Windows RT 8.1, dubbed Windows RT 8.1 Update[7] added a search button to the Start Screen, as well as the taskbar on the Modern UI, and a title bar for Modern UI apps.
