I thought I would try out LogonStudio ( v.1.7.0 ) on my notebook running Windows Vista Ultimate , the problem I have is this ..
When I select .. Load
then go to my wallpaper folder and find a jpg image I want to use as my log in screen , when I click '' any '' jpg image
I then get this box on screen ..
Unable to Extract XP logon File
LogonStudio was unable to decode the xp logon file

Thanks
