The first version of Windows Light was released in 2004.  Over the years, this software has gone through a series of upgrades and enhancements to keep pace with developments on the Windows platform and the wider use of alternative internet browsers.  The current version, Windows Light 2018, provides screen reading features and functionalities in Windows XP up to  Windows 10 (both 32-bit and 64-bit). It also supports Word, Excel and Powerpoint in Office Xp onwards up to Office 2013.  For internet browsing, it  supports Firefox and Google Chrome in addition to Internet explorer.
