Since I have windows 7 on one laptop & windows 10 on another, I want to switch the desktop to XP. I want to do this because I have a lot of older but expensive software and some excellent printers and scanners which won't work at all on windows 10 and which were very 'glitchy' on Windows 7 but it all worked perfectly on XP. I have a 64 bit HP Pavilion Elite HPE-210 which has a windows 7 operating system which I want to replace with Windows XP.
