more like saying can we put windows xp on a windows 7 machine. reason why is because the hardware is likely better and the fact that xp is the most stable (imo) os windows has released. it has had 3 major service packs along with a host of bug fixes and patches. Windows 7 has had only 1 along with some paches and a buggy ie 9. of course this anology isnt the best cause windows xp can barely address 4GBs of RAM but ma point is the old os which is MATURE will work better and be less buggy then the new OS which may be ditched as soon as some new CEO decides they need a new direction.
