Sindows 4

Sindows 4 is an Unsupported SubOS made by Sintendo in 2008. It is the first major release of Sindows (now known as Shutters) to include Advanced Features like Internet, Games for Sindows Live, and NOL Instant Messenger in Sindows itself.

Programs
Sindows 4 includes many new programs like: There was some controversey surrounding Sintendo's decision to remove the Dos prompt that was in Sindows 3.1 and earlier from Sindows 4. Sintendo said that it was to make the SubOS more stable, but others said that a Dos Prompt was a essential feature of a SubOS. Sintendo responded by saying that they would emphasize Sindows Media Player in new versions of Sindows.

Support
Sindows 4 is well known for being Unsupported on the same day as Windows XP. Sintendo now discourages all people from using Sindows 4 in any case. Despite this, Sindows 4 is still found in libraries and schools that cannot afford Shutters FM. Sintendo has started the LCPC program to get Shutters FM into schools, libraries, and the Third World.
