+ Introduction +[Introduction] Welcome to NVDA!

NonVisual Desktop Access (NVDA) is a free and open source screen reader for the Microsoft Windows operating system. Providing feedback via synthetic speech and Braille, it enables blind or vision impaired people to access computers running Windows for no more cost than a sighted person. NVDA is developed by [NV Access https://www.nvaccess.org/], with contributions from the community.

++ General Features ++[GeneralFeatures] NVDA allows blind and vision impaired people to access and interact with the Windows operating system and many third party applications.

Running the file you have just downloaded will start a temporary copy of NVDA. You will then be asked if you want to install NVDA, create a portable copy or just continue using the temporary copy.

If you plan to always use NVDA on this computer, you will want to choose to install NVDA. Installing NVDA will allow for additional functionality such as automatic starting after logon, the ability to read the Windows Logon and Windows security screens (which cannot be done with portable and temporary copies) and creation of Start Menu and desktop shortcuts. The installed copy is also able to create a portable copy itself at any time.

If you want to take NVDA with you on a USB thumb drive or other writable media, then you should choose to create a portable copy. The portable copy also has the ability to install itself on any computer at a later time. However, if you wish to copy NVDA onto read-only media such as a CD, you should just copy the download package. Running the portable version directly from read-only media is not supported at this time.

++ Portable and Temporary Copy Restrictions ++[PortableAndTemporaryCopyRestrictions] Apart from the inability to automatically start during and/or after log-on, the portable and temporary copies of NVDA also have the following restrictions: - The inability to interact with applications running with administrative privileges, unless of course NVDA itself has been run also with these privileges (not recommended). - The inability to read User Account Control (UAC) screens when trying to start an application with administrative privileges. - Windows 8 and later: the inability to support input from a touchscreen. - Windows 8 and later: the inability to provide features such as browse mode and speaking of typed characters in Windows Store apps. - Windows 8 and later: audio ducking is not supported. -

++ Installing NVDA ++[InstallingNVDA] If installing NVDA directly from the NVDA download package, press the Install NVDA button. If you have already closed this dialog or are wanting to install from a portable copy, please choose the Install NVDA menu item found under Tools in the NVDA menu.
