content: Bought a brand new ThinkPad P50 recently.  My OS options were Win10 or Win7 preinstalled via downgrade rights.  You can probably imagine what I'm running.  Win7 is refreshing in its simplicity.  I had forgotten how good it is. FYI, for anyone looking for a Win10 alternative, Win8.1 really isn't that bad, and you can still get virgin install DVDs / keys for it.  Just do what I have done: 1) Install classic shell first thing.  Can't imagine using 8.1 without it. 2) Do the registry hack that turns on "other user" logins.  This avoids the metro / tiled desktop.  I use 8.1 daily and never see it. 3) Turn off automatic updates.  Screen all future updates before installing them. 4) Execute Aegis to clean out all the shit. 5) Execute Never10 to flush out any waiting copy of Win10 and tweak a few group policies that (for the moment) tell Windows Update to never upgrade to Win10. I'm set until my CAD application provider stops providing support for Win8.1.  They just stopped supporting XP, so I think I'm covered.  If I am ever forced to go to Win10 for the CAD stations, they will become CAD appliances (they will only run the CAD apps) and I'll go old school -- use a KVM switch to switch between the Win box and a Linux box used for everything else.
