Many of the hospitals my previous company maintains still use XP for frontend terminals in the pharmacy, payment registers and some kiosks.
Vista was a steaming pile anyways (Hello ME 2.0).. Microsoft seems to be getting into a every other release is decent pattern now (see Windows 7 vs 8). :|
im afraid noone , microsoft or nvidia support vista at this point :(
M$ still supports Vista. Mainstream support ended in 2012 but extended support is good for 3 more years.
I still use Vista on my personal desktop PC. Still doing great.
