Windows 10: Logitech K350 wireless keyboard input lag

So, I have a problem with my Logitech K350 wireless keyboard. It was working fine for years, then recently I started to regularly get input lag, sometimes it's brief, sometimes the keyboard is unresponsive for seconds and lasts for a while. It is very annoying and definitely seems to be a Windows 11 issue, but couldn't figure out what and not to bash Windows, but -frankly- this OS doesn't give any easy to use tools to provide meaningful troubleshooting.Before I am asked / pointed to certain areas, let me tackle the obvious questions:Your battery is running out.No, it doesn't tried with differ

Keyboard input lag (Logitech K270 wireless keyboard, Windows 10 20H2)

Hi there. I've got yet another Windows 10 problem. lol

This time it's my keyboard. I'm using a Logitech K270 wireless keyboard, on Windows 10 Pro 20H2. I have been experiencing keyboard input lag off and on for a couple months now, and I've searched for possible solutions, but none so far have worked. I was hoping you guys could suggest some fixes.

Here's what I've tried, based on the suggestions I've found on the web:

• Updating the keyboard/dongle's drivers (there are no drivers on Logitechs's site, oddly) and firmware. Nope.
• Swapping USB ports. Nada.
• Unplugging any extraneous USB devices. Zilch.
• Checking the batteries. No joy.

As I was typing this it was lagging here and there. It's a bit disconcerting. Anyway... I don't think I missed anything, but if you need more information or diagnostics, lemme know and I'll upload 'em.

Keyboard input lag (Logitech K270 wireless keyboard, Windows 10 20H2)

I do, actually. I have another Logi keyboard and mouse, as well as wired off-brand input devices I can test.
I had updated the BIOS recently, less than two months ago. I can check in case there is another update.
Drivers seem to be current, as it states that "the best drivers are already installed," for the Logitech USB Input Device (Logitech-branded) and the two HID Keyboard Devices (Microsoft-branded) I see in the Device Manager. Logitech doesn't have any drivers for download directly from their support site, so I am stuck with the ones Windows installed. All they have is the Setpoint software and Firmware Update tool. Device installation settings is already enabled to download device icons and apps, and the option to automatically download drivers via Windows Update is also enabled (and I've checked for updates a few times over the past few weeks, nothing except a few minor patches.
Here's what's been updated recently:







I'll try the other keyboards. I can't say for sure IF the lag will affect them (as it seems pretty intermittent with this one, and I haven't had any at all while typing this whole response.
