Drupal added support for IIS in 2010 and we have supported that and WAMP (Running Apache and PHP on Windows). Unfortunately, we have never been able to provide automated testing for these environments. And since 2010, the use of Microsoft products for hosting websites has declined. Because of this, the Drupal core committers propose drop support for Windows when used on production web sites in Drupal 11.
Support for development on Windows will continue. Drupal will continue to accept bug reports for Windows used in development environments,
The following links show the usage statistics used when making this proposal.
- Microsoft-IIS usage was 14.3% in 2012 and is 5.1% .
- Windows server usage was 36.5% in 2012 and is now 16.1%.
- Microsoft Azure does not support PHP, and recommends Linux on Azure instead.
