Part of the problem is that many companies are still in the process of rolling out Windows 7 across their organisation, Silver said, and are now suffering from "migration fatigue".
"We don't see [Windows 8] as being a big enterprise play," he told V3.
However, Windows 8 also includes many features that IT managers in particular would dearly love to get their hands on.
Notable among these are the Reset and Refresh functions, along with Windows 2 Go, which allows the operating system to be run from a USB key, and upcoming support for touch-screen apps in Microsoft's RDP remote screen protocol.
The Reset and Refresh functions, in particular, could save hours of work for hard-pressed IT staff.
Reset allows an administrator to return a PC to its factory state, removing all user data, which could prove invaluable when preparing a system for a new employee or decommissioning a system at the end of its life.
Meanwhile, Refresh can restore an ailing PC to a working state in as little as five minutes without removing any user data or customisations, providing end users with a self-help tool that could cure many PC problems.
"Refresh takes all data, files, personalisation and Metro-style apps, picks them up, re-paves the operating system underneath, then puts them back in place," said Gabriel Aul, director of programme management for Windows Fundamentals, speaking at Build.
Microsoft also demonstrated at Build how a Windows 8 PC can boot from cold in a matter of seconds, and how new boot-level security can prevent Windows from being compromised by malware on USB sticks and other removable storage.
