Hey all. After trying out the default Colemak install at https://colemak.com/Windows I realised that many keys were bound by default to the US equivalents, such as the pound sign, hashtag, tilde, pipe etc. I whipped up a UK derivative in MKLC based on this that changes these characters back to the UK versions. Because it's a Windows-based solution, many programs can notice that you're using an alternate layout and change your default keybindings off the bat or even change keybindings that you wouldn't be able to customise at all otherwise. This is in contrast to a programmable keyboard or AutoHotKey (I haven't tried it, but I doubt programs check for it) which isn't built into Windows.
This doesn't remap Caps Lock to backspace.Try the registry remappings at https://colemak.com/Registry_remapping (or use a programmable keyboard, they're great!).
EDIT: Per this thread, I've made a version of Colemak UK that does remap Caps Lock to Backspace without any fancy registry hacks. A must-have in my opinion, but both options remain here for choice!
'cmkuk' - the version that does not remap Caps Lock
'cmkukb' - the version that does
