Running SSH daemon in Windows 7

Despite being Linux (fan)boy generally and running Fedora on all in-house laptops, I've decided to keep Windows 7 on my newly acquired Acer Revo RL100 media centre PC. I am fairly happy with it and don't feel the need to switch to Linux distro on such PC anyway. However, since my (ir)regular backup policy heavily relies on rsync which pushes data from my laptop over ssh to external USB drive attached to media centre PC, I was looking for a solution that works in Windows 7. Surprisingly, there is one and works pretty well. Phew!
