Microsoft's new operating system, Window 7, goes on sale on 22 October.
Microsoft says the new system has been vigorously tested in order to avoid many of the bugs that caused problems in its previous operating system, Vista.
NZ managing director Kevin Ackhurst says Windows 7 will help companies spend less on IT, because it can be installed on older computers.
The BBC reports many of the features take into account multimedia applications and the fact that users are beginning to store their data on the internet.
Windows 7, formerly codenamed Blackcomb and Vienna, is being released less than three years after the launch of Vista.
The operating system will be issued in six separate editions.
The versions PC users are most likely to see on shop shelves are the Home Premium and Professional editions.
The BBC reports other versions are aimed at users in developing nations and corporate customers.
All but the most basic edition of the software will be available in 32 and 64 bit versions.
Those buying a family pack of Windows 7 will be able to install the software on up to three PCs.
