While I have not found a solution, someone else, in another forum asked about upper and lower registers in the registry. It seems to me I did this with Win 95, Me, or XP long ago.
I really think I will wait till I Have the time and then put a new bigger drive in and load my new Vista 64 Ultimate. I intended to upgrade anyway, I just have several MS programs like Office '07, Street and Trips '08, Win Flight Simulator X, that I will have to re-install and re-activate. Lazy mainly.
