I have installed TuneUp Utilities 2010 on Windows 7 and it works like a dream! However, one question I would like to ask is, in the section where you can change your logon screen, it says that TUU is also compatible with Stardocks LogonStudio XP logons screens. I can't see how this can be as TuneUp Utilities logon file extensions are totally different to the LogonStudio XP file extensions for their logon screens and thus, they don't work? Also, in TuneUp Utilities, you have the option to make your own logon screen but again, if it's a .jpeg you are working with, I can't see how this will work as it wont be the correct TUU 2010 logon file extension? Apologies for being so thick but unless I ask these things and hopefully get an answer, I shall never know the reasons as to why it doesn't actually work? I have downloaded and installed LogonStudio XP and downloaded some of their logon screens but that seems to defeat the whole idea of TUU 2010 logons being compatible with Stardocks LogonStudios XP logons, as they just don't work together. So I presume it's just a case of using one or the other as the two programs certainly wont work together as far as logon screens are concerned. Cheers for any help in advance. Mike.
