As Google takes it up to Microsoft in the operating system market, Microsoft is set to launch a “Family Pack” licence which will allow the software to be loaded onto multiple PC’s in a home.

The new Windows 7 licensing agreement, which has already been seen by several resellers and IT distributors, signals such an offer.

In the US online retailers have already listed a Windows Home Premium Family Pack Upgrade, as a pre order.

When asked about the family pack, a Microsoft’s official said “We will continue to work with our partners and expect to have other great offers in the future as we lead up to and beyond general availability,” a spokesperson said in response to an inquiry about the Family Pack. “We have nothing to announce at this time.”

Apple recently said that it will offer the family pack of its upcoming Snow Leopard Mac OS X for US$49, as an upgrade from the existing Leopard operating system, for installation on up to five computers. Upgrading a single Mac from Leopard to Snow Leopard will cost US$29. Snow Leopard is due in September.
