Do Logon work with Windows XP Pro?

Yes it does.

Do you see a Windows logon screen at all (the default one)? Or can you just not see the logons you've downloaded here.

If it's the first: make sure you've not connected to a domain network. Logons only work with workgroups.

If it's the second, make sure that the LogonXP program is installed correctly. Try uninstalling and reinstalling it. If that doesn't do it, try installing the logons manually: rename the .logonXP extension to .zip then unzip it normally and move the files to a new folder in the LogonStudio directory.

Hope any of this works.

Yes I log on domain§. So it will not work?

No, Windows XP logon screen doesn't work when you're connected to a domain. You get the Windows 2000 style of popup logon window. No way around it, sorry.
