You could probably export a Registry file that has all your settings and then import on a new machine.

The last time I used windows a bit (I think it was around the Planetside 2 launch...), I noted down this:

# set up for putty: # From: http://mshnitzer.wordpress.com/2009/10/09/export-putty-setti... comment:

reg export HKCU\Software\SimonTatham putty.reg reg import putty.reg

I'm not sure what's the standard now, but I also always set "use ssh protocol v2 only" -- and you probably should too (on the off chance that you have some ancient device that doesn't handle version 2, you should probably make an exception in that profile).

if you are a putty user, do this. its very time consuming to set up putty especially colors but its easy to keep all your settings in a reg file.

The fork I'm just about to patch is FuTTY - https://github.com/FireEgl/FuTTY which includes save-settings-to-file. The screen resizing behaviour (as a result of Screen's +flow command) might drive you crazy though.
