can skim more of your money. If they had left the command set in Vista, Win 7, and Win 8 the same as it was in Win XP all that software and hardware designed to work perfectly with Win XP would work perfectly with them, but Microsoft made a deliberate choice to make them incompatible so that software would not just transfer over and they could now sell you new copies of MS Office that will work properly because the older version of MSO won't work properly with the new versions of Windows. Many businesses have mission critical software and / or hardware that works perfectly with Win XP and there is NO new version that works on Win Vista, Win 7, or Win 8, thus they have NO option but to stay with Win XP. In some cases there are new versions, but that requires a significant outlay of extra cash in a poor economy when staying with what they have continues to work perfectly, so why spend the money just because Microsoft want to rip them off.
