Momenteel wordt Windows.NET 1.0 (codenaam Whistler) door beta-testers getest. Microsoft Whistler 1.0 zal in de tweede helft van 2001 in de winkels moeten liggen. Windows.NET 2.0 (codenaam Blackcomb) moet een jaar na versie 1.0 in de winkels liggen. In beide versies zal IE weer geintegreerd zijn, meldt Microsoft."
Microsoft Corporation posts its first beta release of Windows.NET 1.0 codenamed "Whistler" for its technical beta testers. Whistler build 2250, which closely resembles Windows 2000 and Windows Millennium Edition ("Windows Me") is the first public release of Whistler. Whistler is Microsoft's initial client and server platform for its Dot NET strategy. From the roadmap, Whistler will be available in H2' 2001.
A next generation release of Windows.NET 2.0 code-named "Blackcomb" will use the Dot NET "user experience," Microsoft says that Whistler will stick with the tried and true Explorer user interface and not offer a complete "activity center" experience as previously expected. However, Microsoft says that Internet Explorer (IE) will become even more integrated in Whistler. From the roadmap, Whistler will be available in H2' 2002.
