What do these Active Desktop changes mean?

This is part of my log, it's just got the things it found. I know why the override for antivirus and Firewall are there, I put them there myself. I have made some changes through TweakUI and think this may be what the Active Desktop things are about but I was wondering what each of these changes means in more basic terms.

The following detection indicates that there is ActiveDesktop\NoHTMLWallPaper registry entry that is not set to dword:00000001.

HKEY_USERS\.DEFAULT\Software\Microsoft\Windows\CurrentVersion\Policies\ActiveDesktop\NoHTMLWallPaper!=W=1
The items under ActiveDesktop are supposed to be a dword:
0 = no restriction
1 = enable restriction
NoHTMLWallPaper = only allow bitmaps (BMP) as wallpaper

See the following article for a more complete description of ActiveDesktop registry entries:

If you did not intentionally set that registry value to allow HTMLWallPaper than you should fix the detection.
