Could credui.dll or other credential-related libraries cause the hang? Need to take a look with Dependency Walker and do some testing… The error is caused by advapi32.dll trying to detect if Fast Startup is enabled (advapi32.dll CheckForHiberboot), because Windows 7 doesn't have Fast Startup something like this happens: advapi32: Is HiberBoot enabled? LogonUI: Who? advapi32: Is that a yes or a no? LogonUI: undefined advapi32: I'll take that as a yes LogonUI: I don't even know how to load that! advapi32: Figure it out yourself LogonUI: ... advapi32: ... LogonUI: ... So in theory it should work with Win8 beta files if that specific build has fast startup and 7 logon screen at the same time. |

I did try a beta version with DUI patches, but it only resulted in there being no login screen |

What if we disable Fast Startup or Hibernation in general, and stub the functionality somehow to just always say no? |

So in theory it should work with Win8 beta files if that specific build has fast startup and 7 logon screen at the same time. I couldn't find any. All the builds with fast startup also seem to have redpill login screen, which means you've got authui.dll and authui2.dll, which just doesn't work. I tried the EEAP version of 8102 (which has redpill removed at compile time), but it seems they only partly removed it (they were lazy) |

this was achieved by doing the same steps to get it booting, but in order to get past the please wait screen ,you have to do some patching, below is my thought process.  if you look inside WluipStartServer, u can see in the call to RpcServerRegisterIfEx, the first parameter takes in a RPC_IF_HANDLE, this function is the same in 8.1's authui.dll, however, the data inside the RPC_IF_HANDLE is different, So i wondered, what happens if i just paste the data from 8.1 to 7's authui.dll?  well it booted up and got past the "please wait" screen, and started working, initially only microsoft accounts logins seemed to show up (have not tested them yet), however after importing the Authentication key from windows 7, the credential provider for local accounts started working, here are the keys that i imported, in a neat little reg file and a patched authui.dll (hopefully this doesnt break any winclassic rules) authui.dll (1.83 MB) 7log.reg (5.29 KB) |

UAC is also broken now.

UAC is also broken now. to work around the uac issue, in hkey classes root/clsid search for authui.dll and find the entry for background and logon, then create a new folder in system32, such as oldauthui and place the 7 authui dll and mui there, then redirect the clsid entries to it |
