If anyone has had more than a couple of Microsoft tools or products installed (or a local install of the MSDN library) side by side, you might have noticed that opening help (hitting F1) or opening, say, SQL Server Books Online causes the help indexes to be re-indexed - this is usually after installing a new product or tool.
This can be a really, really time consuming exercise!
Does anyone know a way to prevent or opt out having combined help indexes?
At best, even just preventing the reindexing at all?
