Microsoft is to take legal action to try to get the application of the European Commission's competition ruling against it suspended.
The action would be taken 'in the coming days', Microsoft spokesman Tom Brooks said.
The Commission fined Microsoft a record €497m in March and ordered changes to its Windows operating system after a five-year investigation into the software group's overwhelming market dominance.
Earlier this month Microsoft lodged a first appeal with the EU's top court against the landmark ruling.
The action aims to annul the commission's decision but a ruling might not come for several years, leading Microsoft to try to get the Commission's 'remedies' suspended in the meantime.
