I still use it (Windows 7 Pro), both at home & for other people that are unable to update (being offline or have limited download).
I also use wsusoffline with PortUp - sometimes one installs an update when the other does not. However, I am now recently preferring wsusoffline as it has a feature where you can automatically reboot & continue update afterwards continuously until completed.
Unfortunately, one PC I updated had Office installed so now PortUp downloads Office updates too (which I don't want but I guess it comes in handy for other people & I have many unused USB thumbdrives).
I now use PortUp every once in a while to check if wsusoffline has missed anything.
