Windows 10: keyboard lag

I have keyboard lag it has become impossible to make posts, draft a letter or anything using the keyboard, it happened out of the blue about a week ago and then came right.
It has come back again 2 days ago and remains. I tried to do a system restore but got the message you dont have any restore points well I should have, I made a lot over the last few months but none recently but they should have been made automatically by the computer. Is there an easy fix? I am using my old desk top/Vista to post this.

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.

 

Random lag spikes

Hi,

We would like to know more about your lag issue:

• What browser are you using when you experience a lag?
• Does the lag occur in a particular game?

In the meantime, we suggest you run the System Maintenance troubleshooter. Here are the steps:

• Press Windows Key + X.
• Click on Control Panel.
• Select Troubleshooting.
• On the left pane, click on View All.
• Click on System Maintenance to run the troubleshooter.

Looking forward to your response.

 

BG processes cause keyboard shortcut lag


Update, as of 12/5/15

After considerable experimentation it appears that the lag will occur when a STORE or (system) SETTINGS app (Calculator, for example) or "store" itself is listed in Task Manager background processes. Kill the process, and the lag vanishes. When the app is actually running, it is listed under APPS, not background processes. Then at random times, often after a sleep cycle or at boot, it will spontaneously appear as a background process - Calculator, Store and possibly others.

Speculated causes of this annoyance are discussed in this article and its embedded links... https://superuser.com/questions/426947/slow-windows-desktop-keyboard-shortcuts/957210#957210 where "Helen" posted a workaround...

Disable SUPERFETCH. Click START, type "services", <enter>, double-click on SUPERFETCH. Stop it. Disable it.

No performance hit has been noted by doing so, and shortcuts launched via keyboard no longer lag. Fingers crossed.
