Hello Zidane24:
Many thanks for responding so quickly.

It is good to know that Audacity will work in Windows 7. I can use it as a backup just in case my Sony Creative Sound Forge Audio 9 doesn't work.
There is no response from Sony Creative regarding the updating of Sound Forge Audio 9 except that they are promoting their new Sound Forge Pro 10 which is compatible with Windows 7. Except the price tag!
I have several old programmes that I hope will work in "compatibility mode" such as: Nero 6, Photoshop Elements 6 and Switch Sound File Converter.
Zidane, please clarify the availability of the "compatibility mode" in Windows 7, Home Premium Version. I haven't been able to get a clear answer on this subject. I gather that it may be confused with the "virtual mode" in Professional/Ultimate versions.
Truly appreciate the help,
