Windows-8.1 64
Sigil 8.4 (can't remember if I used 64 on this...or if it's even available....I usually do
)
Sometimes:
Firefox (32) - for those W3School references
Skype (32) - just in case someone wants to talk...
Dropbox (32) - because it's always freaking running!!! gah
and other miscellaneous system drivers
