Other Info: Also have an old but important XP SP3 machine still running - Optiplex 755 Desktop w 4GB RAM and 500 GB Momentus XT hybrid HD-SSD, held together with duct tape. Used the registry hack to get more updates through "XP Embedded" or "POS" so now the machine rings like a cash register and the CD drawer opens to give change.
