In-place upgrades that used to take 60 minutes of IT time take only 5 minutes, he says, which is one of the main reasons Forrester gives Windows 10 such a high ROI in the most recent Total Economic Impact study commissioned by Microsoft. “It was already very good, at 188 percent in the first TEI study, and it’s now improved to 238 percent, which reduces the payback time even further.”
The Forrester study also shows that Windows 10 takes 20 percent less IT time to manage and gives mobile workers a 25 percent improvement in productivity — and it does deliver the security improvements enterprises need, thanks to features like Device Guard and Credential Guard. “They see about a third fewer security related issues that they have to follow up on,” Dewar says.
