Dutch author Raymond Comvalius has been one of the fastest out of the blocks with his new book, Windows 7 for XP Professionals.

His timing couldn't be better. Most businesses simply didn't bother with the delights of the Vista client, leaving the XP-to-7 upgrade path as their most obvious, practically mandatory, next step.

"I don't think Windows Vista ever got significant support from the business market," says Comvalius. "As a consultant, I have designed the Windows Vista client for a large bank in the Netherlands. My impression is that this was one of the very few large Windows Vista deployments outside of a few IT and consultancy companies. My estimate of the percentage of business XP users compared to business Vista users is about 90-95%.

"I think business got stuck with XP because of Vista's poor entry on the market. It contained too many non-appealing changes that could not make up for the improvements made. Poor performance on the then current hardware and netbooks entering the market created an even worse situation. I always say that Vista had a bad first impression and you only have one chance to make a first impression."

Apart from his consultancy work, Comvalius trains IT pros, supports the TechNet Forums for Windows 7 and writes news articles for the ever-excellent techie website bink.nu. The author reckons that the main challenges when businesses move from XP to 7 are application compatibility and learning the new deployment tools and mechanisms involved.

"A lot of system admins will be surprised when they find out how much Windows 7 differs from Windows XP," he says.

Windows 7 for XP Professionals is published by a small imprint in the Netherlands Books4Brains. So does his local experience have any bearing on his subject matter?

"The book is based on my experience designing the next generation Windows client for a Dutch bank," says Comvalius. "You can call this a European perspective, but I don't think the challenges are really different when you do this anywhere else on the planet."
