Changes[edit | edit source]

Windows Runtime[edit | edit source]

The beginnings of the Windows Runtime, such as the HSTRING type, an API resolver for the Windows Runtime, class activation and deactivation, and a class cache that matches CoClassIds to actual APIs, have been added to the ole32.dll binary. However, it is likely that there were no actual user-facing Windows Runtime APIs at this point.

Notes[edit | edit source]

This build's Boot Manager for AMD64 is production signed (by the SHA1 certificate chain).
