When I have to use Windows 7, the first thing that really puts me off is the dolls-house-y login screen. It’s so clutzy as to be annoying, and I didn’t realise until today that it can be gotten rid of. Which makes this an essential thing to do on any Windows 7 system you are unfortunate enough to have to use. You can do it by poking around in the registry, or by running this svelte utility.
