Do you use Windows Store/Metro Apps or, for example, Internet Explorer, and are you fed up with automatic word correction, such as trochu > troche, telefony > telephony, or i > I? I will help you set up Czech so that this should no longer happen. The first thing that probably comes to mind is to turn off autocorrect, as I have done in this picture:
However, at least for me, this did not help. I had to set Czech as the input method. If you have an English version of Windows, enter this path into the address bar in Windows Explorer: Control Panel > Clock, Language, and Region > Language. A window like this will pop up:
Here I added Czech, which is now already listed. And that still was not enough, not even moving it to 1st place. I had to set it in the menu that slides out when you move the mouse to the bottom right corner and choose Settings (the last item):
Select Czech here, and Windows will no longer think you are typing in English and will stop correcting you. However, it may happen (it happened to me) that your region settings switch to match the Windows language. In that case, in the Region dialog in the Control Panel you will see something like this:
So instead of 15:45, the time will be displayed as 3:45 PM, and that throughout Windows, including applications that take over this setting. Instead of Match Windows display language (recommended), choose the setting you want.
That is all – if you know a faster way to do it, let me know in the comments.
