Features

Login Screen

The Login Screen in Neptune is an HTML and Javascript based UI. The Login Screen files can be found in logonhta.dll. Installing Internet Explorer 6 on this build usually causes the login screen to stop functioning.

User Accounts Panel

Another HTML and Javascript based UI, pretty much an early version of the Windows XP one. The source code for the applet is contained in nusrmgr.cpl.

Help Center

The Help Center in this build appears to be a direct copy from an early Windows ME build, as the internal branding and help text often contains references to "Windows Millennium". It is run by MSHTML and uses .htm and .xml files for most of the content, as can be seen in the data folder C:\WINNT\PCHealth\HelpCtr\System.

There is an inentionally commented out Windows 2000 Help Link (same help as the windows 200 RTM) in the homepage.htm code and the system restore Link points to a missing exe in the wnnt directory

The database is a .mdb file and can be edited with Microsoft Access (after Whistler 2202, Microsoft switched to a different file format that doesn't allow easy editing); copying the database from early Windows ME builds should add the full range of support topics, however some broken help links will show up.

Using the HCupdate.exe in the binary folder and a properly configured .cab file allows updates to the Help Center components.

Auto Update

Microsoft Autoupdate in Neptune is hidden away in the c:/WINNT directory named wuauclt.exe (That could stand for Windows Update Auto Update Client) This is another of the HTML applications and the UI code is storeed in wuauhtml.dll

Activity Centers

To install the Activity Centers in this build, follow these instructions:

• Put your Neptune installation CD into your CD drive.
• Click Start, Run or press Windows Key + R to open the Run dialog.
• Type in regsvr32 X:\i386\accore.dll (where X:\ is the drive letter of your CD drive) and press Enter.
• Now you can find the files in %WINDIR%\Activity.

You can set the activity centers as a background, as it is probably meant to be, by doing the following:

• Right click the desktop, click properties and go to the Web tab.
• Put a tick in the box with: Show Web content on my Active Desktop.
• Click the "New" button and browse to the activity center's main homepage (%WINDIR%\Activity\Start\StartPage\start.htm).
• Maximize the new screen at the desktop by hovering over the top with your mouse and clicking the second right button.
• Optional: Remove the icons by right clicking in the empty space on the desktop, hovering over "Active Desktop" and clicking "Show Desktop Icons". Then place your mouse over the left border and stretch it as far left as possible or click the third right button.

After many years, Extensive file edits, Lots of research and trial and error, Ex-BA member KenOath was able to fix the Activity Centers as close to what Microsoft intended.
