I want to use the Dvorak keyboard layout at work (I already do at home) but I often need umlauts so the built-in US Dvorak isn't enough, and punching in the umlauts' Alt-codes gets tedious really fast.
It's a corporate Win7 computer with security policies that forbid installing files in system32. All keyboard software I've found needs to write to system32, and I don't think the security people would grant me an exception for this.
Are there any keyboard solutions that can be installed under these limitations?
Alternatively, I've looked at physical keyboards like the Typematrix 2030 but they are also "just" keyboards and don't have any internal remapping. They don't appear to Windows as a normal layout while presenting Dvorak to me -- and even if they did, it would be US Dvorak, so again missing the umlauts. I've only found the FingerWorks TouchStream to be capable of that feat, but it's very different from a regular keyboard.
