I just update my Nokia Lumia 830 to Windows 10 Technical Preview, but I can't disable Windows keys vibration
How I can fix this ?
Go to Settings > Extras > Touch. There you should see the option to turn it on or off.
Try Updating Extras. I faced same problem on my Lumia 535 when I did upgrade on Windows 10 but through official Upgrade Advisor app. This caused some bugs in extras just after upgradation but when I updated Extras from the Store app it resolved almost 95% issues. See this . Updated Touch successfully turn vibration on and off.
