Keyboard delay, where letters appear a beat after you press the key or you have to hold a key before it registers, makes typing on Windows 11 frustrating. The most common cause is an accessibility setting called Filter Keys that gets turned on by accident. Other culprits include wireless connection problems, drivers, and a busy PC. Work through these fixes in order.
Quick answer
Go to Settings > Accessibility > Keyboard and turn off Filter keys. If the delay continues, check the keyboard’s batteries or connection, adjust the repeat delay in Keyboard Properties, and update or reinstall the keyboard driver.
1. Turn off Filter Keys
Filter Keys tells Windows to ignore brief or repeated keystrokes, which helps people with hand tremors but feels like lag for everyone else. Holding the right Shift key for eight seconds can turn it on without you realizing it.
- Open Settings with Windows + I.
- Go to Accessibility > Keyboard.
- Turn off Filter keys.
- Click the arrow next to it and turn off the keyboard shortcut option so it doesn’t switch on again by accident.
While you’re there, check that Sticky keys and Toggle keys are off unless you use them.
2. Adjust the repeat delay and rate
If the problem is that holding a key takes too long to start repeating, change the repeat settings:
- Press Windows + R, type control keyboard, and press Enter.
- On the Speed tab, drag Repeat delay toward Short.
- Drag Repeat rate toward Fast.
- Test in the box provided, then click OK.
3. Check wireless and Bluetooth keyboards
- Replace or charge the batteries. Low power is a top cause of lag on wireless keyboards.
- Move the USB receiver closer. Plug it into a front USB port or use a short USB extension so it’s in line of sight of the keyboard.
- Reduce interference. Keep the receiver away from Wi-Fi routers, USB 3.0 hubs, and external drives, which can interfere with 2.4 GHz signals.
- Re-pair Bluetooth keyboards. Go to Settings > Bluetooth & devices, remove the keyboard, and pair it again.
To rule out the keyboard itself, try a different keyboard, or plug a wired keyboard in. If the other keyboard works perfectly, the original one or its receiver is the problem.
4. Update or reinstall the keyboard driver
- Right-click Start and choose Device Manager.
- Expand Keyboards.
- Right-click your keyboard and choose Update driver > Search automatically for drivers.
- If that doesn’t help, choose Uninstall device and restart the PC. Windows reinstalls the driver automatically.
For gaming or premium keyboards, install the latest software from the keyboard maker, which may include firmware updates.
5. Check if your PC is overloaded
If the whole computer feels slow, keyboard lag may just be a symptom. Press Ctrl + Shift + Esc to open Task Manager and look at CPU, memory, and disk usage. Close programs using a lot of resources, and restart the PC if it hasn’t been restarted in a while.
6. Run the keyboard troubleshooter
Go to Settings > System > Troubleshoot > Other troubleshooters and run Keyboard if it’s listed. Microsoft has been replacing older troubleshooters with the Get Help app, so this option may not appear on newer versions of Windows 11.
7. Turn off Fast Startup
Fast Startup keeps some drivers in a saved state between shutdowns, which can carry over glitches. Open Control Panel > Power Options > Choose what the power buttons do, click Change settings that are currently unavailable, uncheck Turn on fast startup, and save.
8. Install Windows updates
Go to Settings > Windows Update and install pending updates, including optional driver updates under Advanced options.
9. Check the power settings for USB
Windows can turn off USB ports to save power, which may cause a wired keyboard or wireless receiver to respond slowly after a pause. In Device Manager, expand Universal Serial Bus controllers, double-click each USB Root Hub, open the Power Management tab, and uncheck Allow the computer to turn off this device to save power. Restart the PC afterward.
If lag only happens in one app
If typing is fine everywhere except one program, such as a browser or game, the app is the problem. Update it, close extra browser tabs, or turn off hardware acceleration in its settings. Remote desktop and virtual machine apps also add noticeable delay over slow connections.

Sticky Keys is a separate accessibility setting that can also make typing feel wrong, and you can turn off Sticky Keys in Windows 11 from the same Keyboard page.
Frequently asked questions
Why does my keyboard work after restarting but lag later?
This often points to a background program using resources or a wireless connection that weakens over time. Check Task Manager and your wireless setup.
Can a dirty keyboard cause delay?
Yes. Debris under the keys can make them register late or not at all. Turn the keyboard over and use compressed air.
Does Filter Keys affect laptop keyboards?
Yes. It applies to every keyboard connected to the PC, including built-in ones.
