I have several computers,an XP PC,and ME PC,and a Vista Laptop,I do alot of photography,so I need allllll of them ,Microsoft is smart,the whole idea of Vista was to make the need for the comsumer to BUY new software,but if you are clever,you can do what I have done many a time,lets say you need a PSP9 Vista Patch,that is what you type into your search engine,and if there is a patch out there for it,you will find it that way.(NOTE-a patch is a small program that when doownloaded will allow your ME,XP program to work with Vista,personally,and this is my OP ONLY, Vista sux,keep the ME and the XP,avoid the vista.
