Windows 11 keyboard lag. Nothing fixes it

Hi there,

Thanks for the suggestion. I also have 16gb RAM but unfortunately the changes made no difference for me.

I agree 100%. I even have lag with my wired devices, in fact I am having to go back over this post and fill in the missing letters.

I don't understand why there is still no fix. I actually wish I had left my PC on Windows 10.

Up until July 2023, I was running my Dell laptop with Windows 10 in two different settings:

1. wired keyboard, wireless mouse (no unifying receiver, no Bluetooth, but I guess some proprietary wireless protocol)
2. wireless K750 solar keyboard and MX Anywhere 2S mouse, both using Logitech unifying receiver

Never had any issues. Ever.

Then, the company had us upgrade to Windows 11.

In Setting #1, the mouse started lagging. Sometimes, killing and restarting Windows Explorer helped for a little while. The receiver is maybe 20 inches away from the mouse.

It's still an open issue.

In Setting #2, the keyboard is lagging. It seems that input is buffered, then delivered delayed for seconds.

The Logitech unifying receiver is connected to an Anker USB hub, which is connected to the laptop's UCB-C port, and it's literally 8 inches away from the keyboard. The issue still happens, but interestingly, the mouse doesn't have any issues.

I have plenty of free RAM, and the keyboard is charged to 100%. In Device Manager, I set all USB controllers to disable turning off power.

Nothing helps.

This is clearly a Windows 11 issue with wireless mouse/keyboard. Whether or not it's a Logitech issue, I can't determine.

Hello there!

I had the same issue and tried the same steps as you but nothing seemed to fix it.

Then I found a solution that worked for me. I am not from a computers background so apologies in advance for the clunky explanation.

Windows 11 (for some godforsaken reason) has too little virtual RAM allocation by default. So if there are programs consuming too much memory, the system puts the keyboard input "on hold" until its done processing.

I increased the VRAM allocation, and the issue was fixed.

Changing VRAM allocation:

Settings > System > About > Advanced system settings > Advanced (tab) > Settings (under Performance) > Advanced (tab) > Change (under Virtual memory) > Uncheck Auto manage paging size > Select Custom size > Enter initial and max values > Set > Ok

I used 9216 MB and 12288 MB as initial and max size for my PC with 16GB of RAM, I suggest doing your own research to find the right values for your PC.

Hope this helps!

This worked for me with wireless keyboard and mouse

Modify the Power Management Settings.

The keyboard might keep regularly disconnecting on its own due to your computer power settings. You can tweak a few power settings to solve the issue.

Here are the changes you need to make in the Power Management Settings:

Open the Device Manager, double-click the Universal Serial Bus controllers option, right-click on the USB Root Hub or Generic Hub and choose Properties.

Switch to the Power Management tab.

Uncheck the Allow the computer to turn off this device to save power option.

 USB Root Properties in the Device Manager

Click OK to save the changes.

Disable Fast Startup on Windows 11, open Control Panel System > Hardware and Sound > Power Options > Choose what the power button does, click on “Change settings that are currently unavailable,” turn off “Fast Startup,” and click “Save.”
