Hi! Me and ephemeralViolette have been in ClassicServ tinkering with system files for the past few hours in an attempt to get the old, non-XAML/DirectUI UAC prompt back, and we did it! Files needed:
https://aubymori.github.io/#!/files/classic-uac(bbcode doesn't parse this correctly)
Once you've downloaded these files, run INSTALL.cmd as administrator and follow the steps on screen.
Cheers! Attachments:

If anyone has any idea why the black backgrounds are drawn, any help would be appreciated. This UAC UI uses DirectUI rather than GDI directly or anything else like WPF or XAML.
I will look into the DUI files of the dialog later and attempt to discover any potential cause.

Tested and confirmed that this in fact does NOT work on Windows 11.
See new update.

We got it working perfectly fine on 21H2 by modifying the DirectUI resource in authui.dll! Turns out it was using an invalid ID for transparent backgrounds with newer versions of Windows 10 or something, so it just ended up drawing black instead.
The link should be corrected in the original post to provide a version to this modified version.

Update: The issue's been fixed. The link now points to a new ZIP which contains the updated files. The ZIP also now contains authui7.dll.mui, which is modified to have Windows 7 strings (e.g. computer instead of PC)

Still does not work on Windows 11?

It may work on Windows 11 if you additionally replace consent.exe with a Windows 10 version, but we haven't tested that.

Does this also bring back the old authentication dialog (for example, SMB shares)?

Hi! Me and ephemeralViolette have been in ClassicServ tinkering with system files for the past few hours in an attempt to get the old, non-XAML/DirectUI UAC prompt back, and we did it!
Once you've downloaded these files, follow these steps:
1. Place the system files where they need to go; DLLs in System32, and MUIs in System32\en-US. (If your system locale is not en-US, download 1607 in your language and grab the MUI files from there instead, and of course put them in the proper locale folder instead of en-US.)
2. Import the registry file provided.
3. Make sure that HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Windows\CurrentVersion\Authentication\LogonUI\TestHooks\XamlCredUIAvailable is set to 0. This should already exist as a DWORD.
4. Restart, and you should get old UAC UI!
Note that this is slightly broken, as you will see black boxes in many places, even with classic theme. Screenshots of this phenomenon both themed and unthemed are shown below. (This is now fixed.)
Cheers! omg im so fucking happy rn i cant believe u guys actually did it |

Is there a way to make the window frames the basic style like in windows 7 / vista?

Does this also bring back the old authentication dialog (for example, SMB shares)? It should, but we only tested UAC specifically. From taking a peek at the disassembly again, it doesn't seem there are any CLSIDs pertaining to such a feature, so I assume they are controlled by the same one (CLSID_AuthUICredUI) as the UAC dialog. My guess has been that UAC uses a lot of the same code as other authentication dialogs anyway.

I tested this in a LTSC 2021 VM, and there is a decent delay between the moment the screen goes dark to the moment the UAC prompt comes up and blings at you. Is there a way to reduce this delay? It's my only gripe with it, it's otherwise perfect.

Okay, so while the XAML side of things shows up fine (regarding the 1607 UAC Prompt), the non-XAML version straight up fails to appear on a non-LTSC release. Don't know what's different here..
Edit: Appears fine on Administrative accounts but not regular. This might be a fairly big tradeoff.
