Not much at the moment. FireFox, EditPad (a text editor), PDF XChange Viewer, IrfanView, and sometimes LibreOffice spreadsheet. When I'm doing tax returns I also have professional tax software running. I loaded the Windog Solitaire game and it took 15 seconds to load. I think FF is being a memory hog, but I mostly blame Windog. I'm running 8.1 now and I'm wary of upgrading to 10. My experience is that every upgrade of Windows runs slower than the previous version. SighWhat kind of processing are you doing that makes it seem so slow?
