Just it's much faster to boot into windows then boot up LiveCD and then install extension.
And there is always something comes down the pike forcing me to use windows for a short time. Clients are picky about Document formats Libre Office not the best for that. And saved data filetypes in other supported programs they use.
And cool about running it in usb vmware. Tho don't have the inkling to do that. As just find setting aside a Win7 partition the easiest and just there solution when needed.
