The decision means Labor leads 76 seats to 74 - winning government by just one seat.
"No one party has a lead here; we've all got to learn to work with each other, even natural foes," Independent Rob Oakeshott says.
Mr Windsor indicated he would support the Labor Party, based largely on the ALP's broadband policy, and how it would positively impact on rural communities.
"You do it once, you do it right, and you do it with fibre," Mr Windsor says, in relation to broadband infrastructure.

Mr Oakeshott also highlighted the importance of broadband, as well as the importance of strong investment in regional and rural education.
Mr Oakeshott says this government is not a mandate, and stressed that this minority government will be different to others seen in Australian history.
"This could not get any closer," Mr Oakeshott says, joking that even his own children were split on how he should vote.
Mr Windsor noted his decision was based largely on how stable the new government would be, particularly in relation to the Senate.
The decision came shortly after another key independent, former National MP Bob Katter, announced he would back the Coalition, but implied the support was not unconditional.
Mr Katter told the press conference he could easily work with a Gillard Government, and may be convinced to side with Labor if the other two independents chose to support the ALP.
