The Japanese computer supplier NEC has officially launched a product to let network administrators downgrade machines running Windows Vista to XP. The OEM first made the product, NEC FlexLoad, available to customers on 25 January. However, the product was officially launched on Tuesday. Customers with a Vista licence can purchase the two-DVD pack for GBP 7, according to David Newbould, NEC UK’s product marketing manager. The first DVD sets up a partition on the hard drive and installs core XP files and drivers, while the second DVD installs the remaining XP files in the partition, said Newbould. NEC recommends that customers burn a Vista recovery CD before installing the XP partition.
