A conclusion to the six year-long European antitrust case against Microsoft is imminent, a European Commission spokeswoman said.
Commission antitrust officials have drafted a final ruling in the case, which may follow the line the commission took last August when it issued Microsoft with a statement of objections.
Microsoft was accused of abusing its dominant position in the software market by obstructing rivals' programs from working with Microsoft Windows operating systems.
The commission also accused the company of shutting out competitors to its Media Player audiovisual software by bundling Media Player into the computer code of Windows.
The commission hosted a hearing in November where Microsoft's rivals were invited to demonstrate how the software giant was distorting the markets they operate in. According to people present at the closed-door hearing, the commission's misgivings about the way Microsoft competes were confirmed in the presentations.
Microsoft also gave its arguments at the hearing, but the real negotiations with the regulators did not start until after it finished.
Negotiations in a case of this magnitude could continue "almost to the last day", said one person close to the commission who asked not to be named.
"They may well continue beyond the ruling," he said, adding that it may be to the commission's advantage to negotiate a settlement during the near certain appeal that would follow a negative ruling.
"They would be negotiating from a stronger position with a ruling behind them," he added.
The draft ruling was circulated to other departments within the commission last week, according to one of the people close to the commission.
The inter-departmental consultation usually takes around a month. Next, the ruling would be circulated among national competition regulators from the 15 member states of the European Union.
Competition commissioner Mario Monti's team will decide on the fine to impose on Microsoft a week before a final vote on the ruling by the 20 commissioners. The case is expected to conclude in March or April.
"As far as the competition department is concerned the ruling is final," said another anonymous source. Other parts of the commission can comment but they rarely change much in an antitrust ruling, he added.
Microsoft is still negotiating with EU regulators.
