Our computers are almost exclusively XP. A select few computers have Windows 7. Some are scattered around that use Windows 98 and 2000.
I think it’s the professional version of Windows 8.
Most of the desktops are Windows 7. The graphics classroom has Macs, but I’m not sure what OS they are. We also have Samsung and Acer Chromebooks, but I don’t really know what those qualify as.
All of them have Windows 7 and run Microsoft Office 2013 or 2010.
All of our high school students have Mac Airs running OS X Yosemite. One of the few reasons to like my school district.
All Windows 7 with Office 2013. We have Chromebooks for in class use only.
