Neues vom freien Windows-Nachbau ReactOS:

Ionescu indicates that ReactOS is nearly 100% binary and API compatible with the Windows 2003 kernel, and that they are aiming for full Vista compatibility. Ionescu attempted to demonstrate ReactOS but only succeeded in installing it after two BSoDs. This alone should make it clear that ReactOS is still not ready for prime time.

Klingt für mich danach, als ob sie sich dem Original schon sehr stark angenähert haben.
