Classic Theme has no wallpaper set by default, that's why your modified Bliss.jp_ isn't being applied.

You should be able to change it using the following regtweak:

[HKEY_LOCAL_MACHINE\Software\Microsoft\Internet Explorer\Desktop\General]
"BackupWallpaper"="c:\\windows\\web\\wallpaper\\custom.bmp"
"Wallpaper"="c:\\windows\\web\\wallpaper\\custom.bmp"

Edit the path and filename to suit your specific needs. If you have already created a new Bliss.jp_ cab file for your custom wallpaper, you should be able to code it as follows:

[HKEY_LOCAL_MACHINE\Software\Microsoft\Internet Explorer\Desktop\General]
"BackupWallpaper"="c:\\windows\\web\\wallpaper\\bliss.jpg"
"Wallpaper"="c:\\windows\\web\\wallpaper\\bliss.jpg"

I'm not sure of the correct file extension since the original bliss file is a bitmap. I think setup will uncab your modified one to bliss.jpg, it's original state, though.

i'll try it on my VMware now

*UPDATE* Wallpaper not applied.

Why does the most easy and straight solution go unthought of....

No need to patch WFP.

No need to deal with .theme files.

No need to replace files on I386.

a. Using batch-file, delete %WinDir%\Web\Wallpaper\Bliss.bmp

b. Then copy over your own BMP using copy commands in same batch-file!

That's all! That's what I do, and it works perfectly. I am in a hurry as of now, but I'm sure the others here will be able to tell you how to do steps a & b unattended.

Things to know:

1. Place your intended new wallpap in "$OEM$\$1\install\temp\Bliss.bmp" or wherever.... just ensure that your .CMD can access it.

2. The file delete+copy should happen at T-12 (cmdlines.txt stage).

3. Remember, remember, remember.... its a BMP to be replaced with another - don't use JPEG/GIF/PNG.

I see what you are saying, however i need to center and change the color of the background. what i was wondering if i can add something into the

[Display] section in the winnt.sif file that could do all of this??
