"Two quick questions:
1. How do I change the boot screen background colour on NT4 (the one which shows the OS ver, Processor type and amount of RAM) from the painfully bright blue to black? Is a registry hack involved or would I have to use resource hacker?"
This I don't think can be done... most resource hack type programs won't work on NT based Os' "Native Mode" operating code since its not in Win32 PE (portable executeable) format afaik, & uses native NT (VMS derived) function calls & its OWN, distinct & separate API.
I could be wrong, but I think not on this one...
"2. How do I change the Windows NT flag logo wallpaper on the initial login screen (the one with the desktop green background) to a picture of my choosing?"
Now, this is pretty easily doable!
"I know the file used is C:\WINNT\winnt256.bmp and the registry value is HKEY_USERS\.DEFAULT\ContolPanel\Desktop\[Wallpaper: REG_STRING]
but when I save a file in .bmp format in the Windows dir ie 'Wallpaper1.bmp' and edit the registry value accordingly to 'C:\WINNT\Wallpaper1.bmp' it still doesn't show."
Want a QUICK hack for it? Replace the one you have now with one of your choosing (backup the original first though by renaming it etc. for example) & then overwrite it & rename it same name with one of your OWN choosing.
"Aside saving the picture in Windows .bmp format with runlength encoding, are there any other limitations ie size or colour depth that need to be set?"
This I think you may have hit on something (ringing a bell here)... I have done that here & have changed the default initial color to black for the background with this:
[HKEY_USERS\.DEFAULT\Control Panel\Colors]
"Background"="0 0 0"
&
HKEY_CURRENT_USER\Control Panel\Desktop wallpaper value
& also my login/logout wallpaper to my own "APKNTClouds.bmp" file...
HKEY_USERS\.DEFAULT\Control Panel\Desktop on the WALLPAPER entry I put mine in here as well... I THINK that is what did it for me for logon/logoff wallpaper being same as desktop one.
