Thanks Ibrahim - I was hoping this was the case. I have found however, when searching for USB sound cards, that some seem to only run under 64 bit machines, and at times info given about products isn't always as clear as it could be - Andy ----- Original Message ----- From: Ibrahim Gucukoglu To: access-uk@xxxxxxxxxxxxx Sent: Sunday, January 06, 2013 10:00 PM Subject: [access-uk] Re: What does Vista registered mean? Hi Andy If the soundcard can run on Vista, Windows 7 or Windows XP that generally means all versions and less as otherwise stated. The registered you are seeing is simply a sign, registered trademark and so forth. All the best, Abraham.

I have found a Creatives one that is compatible with Windows 7, Vista registered, and XP 64 bit. This laptop is running Vista home premium, is that different to registered? - Andy
