There's a report on Silicon.com that a senior person at Microsoft has dismissed concerns over software that may not work with Vista Service Pack 1.

The last time I looked at the Microsoft KnowledgeBase article with details of known problems it was as bad as it sounds; in fact all of the programs had updates available to solve the problems.

As long as you do some basic research into the security software on the computer there shouldn't be a problem as there is likely to be a reasonable amount of time before it becomes a mandatory install.

But then, that's the problem. It shows that software developers still haven't made the leap to a truly consumer orientated culture. I don't have to make lots of checks before upgrading the firmware on my PVR.
