Apple released updating software to help Vista users access their purchased iTunes songs last week — but continues to warn Windows users to delay their upgrade to Microsoft's new operating system.

The company is reassuring Vista users that it is preparing to "address a number of iTunes compatibility issues in the next release of the software".

While it may work now, Apple recommends customers wait to upgrade Windows until after the next release of iTunes, which will be available in the next few weeks.

Customers who have upgraded to Windows Vista and are experiencing issues playing iTunes Store purchases should download and run the iTunes Repair Tool for Vista after re-installing iTunes 7.0.2, Apple reminds.

Microsoft – which offers its own devices for music – says it has a team working with Apple to address any existing compatibility issues.
