I am having problems with my keyboard, making double symbols.

As far as I know and have been used, that's the way the Danish keyboard layout works.

To test it I also changed the layout to Danish in three machines, Windows 7 & Windows 8 virtual machines and this laptop I am using now running Windows 8.1.

It works exactly as I have described: First press of accent (´) inputs nothing on screen, it remains in buffer waiting the next key to be pressed. Accent + E gives É as it is supposed to do, accent + SPACE gives a single accent.

I do not understand your issue. Writing Danish you do not need single accent character. Writing in another language you can switch to respective layout.

That is a hardware (keyboard) issue, not caused by software (keyboard layout). I suggest you test that keyboard on another PC.

Okay so I'm having the exact same problem as this guy. And 2 weeks ago, my keyboard was acting normally (single use of ^^``~~¨¨) as giving single output to buffers, even on danish keyboard layout. Now it's acting as being said in this thread. I've tested 3 keyboards that all act the same on my computer. I've also tested these keyboards on other computers with same keyboard layout as mine and they work as intended (as OP is saying). Danish keyboard have never, in my experience, made a double symbol when typing something like circumflex. All worked perfectly fine till about 2 weeks ago. I haven't tried formatting. But I've used CCleaner, Spybot Search&Destroy, Ad-Aware and AVG antivirus. Still nothing.

Edit: I tried following the guide in the other post. With no luck either.

Yet another edit: It does this with what ever language I chose, english, french, spanish, danish. All the layouts. Funny thing is though, when I look around the internet. Most danish people have this problem. Wich is weird, cause they are experiencing a sudden change. It's not when they buy the computer and set it up, it's usually after months of working normally (without the double writing), it suddenly starts doing it. Usually after a restart people are reporting.
