Abandoned build 7048 x-64 on Laptop

There is another new feature in 7048. Apart from allwing a smaller foorprint, I cannot see any real r4eason for it. I always use my oldest laptop (64bit totally!) for initial installations. I was very disappointed to find that, whilst I had no problems with two equally old Laser printers, namely a HP122 and an HP2100, they failed to find drivers in 7048.
I started to mess around in the "add a device/add a printer section. Neither printer was listed. <i am afraid I cannot be more informative, at this stage, as to what triggered it, buy suudenly the window went gray and said, "updating your hardware list" I thought I would be patient. After about ten minutes the window returned to normal and there, among so many other new items, were both of my printers! They installed and worked perfectly without any third party intervention.
I think it has something to do with this new update feature: Control Panel - System - Advanced sytem settings. - Hardware -
