I have a 2016 15-inch Macbook Pro, on which I installed Windows 10 via Boot Camp. But it's often slow to respond to my keystrokes. There's a slight delay before what I type shows up on screen, barely noticeable, but I find myself slowing down for the OS. I don't think this problem is limited to just one app. Rebooting into macOS makes it responsive, so it's not a hardware problem.

I've rebooted the machine, applied all available updates via both Apple Software Update and Microsoft Store, but the problem still occurs.

Has anyone else encountered this? How do I debug and fix this, before I give up and delete the Windows partition?

  • Try this: Check in Control Panel > Ease of Access Center > Make the keyboard easier to use. Under "Make it easier to type", uncheck "Turn on Filter Keys" if it's on. – harrymc Sep 28 '18 at 11:39
  • If the keyboard is on Bluetooth see this article. See also this article. – harrymc Sep 29 '18 at 8:07
  • It's the keyboard built in to the laptop. And it's not a dust problem as the second link says, because that affects macOS as well. – Vaddadi Kartick Sep 30 '18 at 2:34
  • What is your driver for the keyboard? – harrymc Sep 30 '18 at 8:20
  • When you say "unresponsive" do you mean that it completely doesn't work? Or do you mean that it intermittently or consistently is slow to respond to keyboard input? I'm asking because the nature of the problem can help indicate where the problem lies. If the keyboard doesn't work at all I would look in one direction, and if it works but with issues, then I would look in another direction. I think I have the same MBP as you that I could test with. – apocalysque Oct 3 '18 at 22:11

I don't have a test system set up to verify my answer. But with the little experience I have with this configuration I experienced the drivers being sort of touchy. But unlike in you're case for me they stopped working at all. Researching that on the web, I found out that people are going through the Boot Camp assistant to get the latest keyboard drivers, that sees to solve similar issues in several cases.

So the solution (that might work) would be to boot into macOS. Then start the boot camp assistant and download the latest drivers storing them in a way they will be accessible from Windows. Boot into Windows and run the downloaded installation program. Most likely a reboot will be required.

I'm wondering if that solves you're problem. Again sorry, I can not verify my answer.

  • Boot Camp Assistant in macOS does not have an update function. Apple Software Update in Windows has all updates applied. Thanks for your help. – Vaddadi Kartick Sep 29 '18 at 3:47
  • @VaddadiKartick Interessting, thanks for the feedback! Here's one of the pages that described the solution I was suggesting. Did I understood it wrong or was the update function discontinued? – Albin Sep 29 '18 at 3:59
  • support.apple.com/en-in/HT208495 says that it's installed automatically, which did happen the first time I booted into Windows. None of the symptoms that page describes like trackpad not working are happening. Seems more like a Windows issue than an Apple one. – Vaddadi Kartick Sep 29 '18 at 7:13
  • @VaddadiKartick but on other pages the symptoms similar to your's were shown, I just can't find the urls again. Anyway I would still try to do it manually just in case it works. Or was the update function discontinued, you weren't clear on that. – Albin Oct 3 '18 at 8:59
  • There's a Windows app called Apple Software Update. It says that there are no new updates. I'll try it again in any case, thanks. – Vaddadi Kartick Oct 4 '18 at 3:36

Sometimes a USB port can just stop working when you upgrade to a new version of Windows. Usually it’s because of a driver problem. You should always check for this problem first.

Fortunately it’s easy to test: simply unplug the keyboard from the USB port and plug in another USB device – like a mouse or an external hard-drive. If that device doesn’t work either, the USB port itself is the problem, and you should skip straight to Method 4. If the device you just plugged in does work, then continue to Method 2.

Have installed your keyboard driver in win10? If not, I recommend you use the software Driver Easy to install driver.
1) Download and install Driver Easy.

2) Run Driver Easy and click Scan Now button. Driver Easy will then scan your computer and detect any problem drivers.

3) Click the Update button next to the flagged keyboard (or USB device) to automatically download and install the correct version of it (you can do this with the FREE version).

Or click Update All to automatically download and install the correct version of all the drivers that are missing or out of date on your system (this requires the Pro version – you’ll be prompted to upgrade when you click Update All). enter image description here

  • Thanks, but this is about the built-in keyboard. – Vaddadi Kartick Sep 26 '18 at 13:44
