Hi,
windows-vista.ms = Whatever the reg fee for it was, extention and "-" hurt it
windows-vista.org.uk = Again, poor ext and the "-"
windows-vista.me.uk = ^^same as before
windowzvista.co.uk = The "z" hurts it, but the best out the bunch
I thought about registering WindowsVista.ms back in May because it was one of the only ccTLDs Redmond had yet to register WindowsVista in. The problem with these names is their inherent trademark problems which is the reason why I decided to not register it back then. It’s difficult to gauge their value though.
windows-vista.ms <--- TM issues
windows-vista.org.uk <--- TM issues and bad extension
windows-vista.me.uk <--- worthless extension
windowzvista.co.uk <-- Borderline...might be something here. low $xx for now, but ya just never know.
