How do I fix a delayed response to each keystroke in Windows 11?

Hi @James Taylor, 

Welcome to Microsoft Q&A forum. 

Thank you for reaching out and providing such a detailed overview of the troubleshooting steps you have already completed. I understand that despite your efforts with driver reinstalls and system file scans, you are still experiencing a significant one-second delay when typing on your Eluktronics MAX-17. 

Based on your report, we would like to isolate whether this issue is caused by Windows power management or a conflict with the laptop's specialized management software. Please try the following two steps to help us narrow down the cause. 

First, we should address the USB Selective Suspend feature. In many high-performance laptops, the internal keyboard is routed through an internal USB hub. If Windows attempts to save power by suspending this hub, it can cause a "wake-up" lag every time you press a key. To disable this, navigate to the Control Panel, select Hardware and Sound, then Power Options. Click on "Change plan settings" for your active plan, followed by "Change advanced power settings." Under the USB settings, ensure that the "USB selective suspend setting" is set to Disabled for both battery and plugged-in modes. 

Second, please check for a conflict with the Eluktronics Control Center. This software manages your RGB lighting and performance modes but can occasionally interfere with input processing. Open your Task Manager, locate any process related to the Control Center, and select "End Task." Test your typing immediately afterward to see if the responsiveness returns to normal. 

Please let me know the outcome of these tests. Once I have your update, we can determine the next appropriate steps to resolve this for you. 

Looking forward to your response.

It sounds like you've already tried several common troubleshooting steps for keyboard issues in Windows 11. Here are a few additional suggestions that might help resolve the delayed response to keystrokes:

1. Check for Background Processes: Sometimes, background applications can cause delays. Open Task Manager (Ctrl + Shift + Esc) and check if any processes are consuming a lot of CPU or memory.
2. Update Keyboard Drivers: Ensure that your keyboard drivers are up to date. You can do this through Device Manager by right-clicking on your keyboard and selecting "Update driver."
3. Change Keyboard Settings: Go to Settings > Time & Language > Typing, and check if there are any settings that might be affecting keyboard input, such as the "Show the touch keyboard when not in tablet mode" option.
4. Perform a Clean Boot: This can help identify if a startup program is causing the issue. You can perform a clean boot by typing "msconfig" in the Run dialog (Win + R), going to the Services tab, checking "Hide all Microsoft services," and then disabling the rest.
5. Check for Malware: Run a full system scan using Windows Defender or another trusted antivirus program to ensure that malware isn't affecting system performance.
6. Test with an External Keyboard: If possible, connect an external keyboard to see if the issue persists. This can help determine if the problem is hardware-related.

If the problem continues after trying these steps, it may be worth considering hardware support or contacting Eluktronics for further assistance.
