US reports that upgrading from NT 4.0 to NT 5.0 will cause problems for notebook users were firmly quashed by Microsoft today.
Nick McGrath, a Windows desktop product manager at Microsoft UK, said: "We'll build it around advanced power management."
He said that Microsoft now had NT 5 in beta one and that it understood the importance of the notebook market.
"We're working very closely with all the laptop vendors now to ensure support and compatibility for NT 4, so that migration will be in place," he said. "In NT 5 we'll have advanced power management facilities and there will be an upgrade from NT 4 to it."
The vendors Microsoft is now talking to include Toshiba, Compaq and IBM, McGrath confirmed.
He said there was no truth in the rumours in the US press that there will be difficulties upgrading.
