After trying the batch file didn't work for me Vista Home Premium so I did the manual replacing of the files and it worked.
for those of you newbies first dl Takecontrol from here http://www.winmatrix...=take ownership
so you won't have to go trough all the bs of clicking a billion times simply to rename the files then
Download the patched DreamScene files as above and unpack to a folder.
Copy DreamScene.dll to %WinDir%\System32\ folder.
Copy DreamScene.dll.mui to %WinDir%\System32\en-US\ folder.
In Windows Explorer, navigate to %WinDir%\System32\ folder.
Right click on themecpl.dll file and take ownership, then Rename the file to themecpl.dll.original.
Copy the patched version of themecpl.dll to %WinDir%\System32\ folder.
Repeat on themecpl.dll.mui file located in %WinDir%\System32\en-US\ folder.
After taking ownership, rename the file to themecpl.dll.mui.original.
Copy the patched version of themecpl.dll.mui to %WinDir%\System32\en-US\ folder.
Create a new folder in %windir%\Web named “Windows DreamScene” (without quotes). This is the location to place all your videos want to set as DreamScene wallpaper, and can be easily configured via Control Panel Personalization applet.
Lastly, import and merge DreamScene.reg to registry. (rightclick file and click on merge)
After patching, right click on any blank space on Desktop, select “Personalize”, then click on “Desktop Background”. Under location, select “Windows DreamScene Content”, and then select a animated video you want.
