I use windows millenium… joking :). I voted win 7.
The cash registers at work run on XP !?! so dont joke… how on earth a POS can run a non-supported OS is beyond me, my XP running laptop runs like total ass, I can barely load a webpage.
… sorry, of topic I know, but I’m in an angry drunk rant mood…
Haha… maybe they just waiting to finish amortizing those registers before replacing them completely. Could be idiots too… we are everywhere bwahahaha!
I still do a lot of development on my XP workstation. It’s already setup and comfy like an old sofa. It can’t run Java 8 without scary warnings about installing it on an unsupported OS… so its days are numbered. Windows 7 still infuriates me in a few small ways… and I have to pay for it where I stick it. 
(I have XP on a volume license.)
Note: my new systems are all Windows 7… not saying I don’t have it. Just that I’m not willing to ruin my comfy sofa yet.
they are idiots, I can crash the till and get admin access …
Well, seems you didn’t get the note… this is a dumbocracy, so bow to your overlords, minion!
