Windows 10: GUI is lagging intermittingly - Apps, web, OS

My laptop has been functioning fine since two weeks ago. It used to run fine with design and 3D drawing tools. However, it has become so agonizingly slow that I could barely use it. Everything taked longer: Windows UI animations, the time for the start menu to appear takes seconds, all contents of the file explorer 10 seconds, apps starting up. It feels like something has been disabled or limited in terms of processing power. I'm pulling my hair out! I checked the energy profile that my laptop is on for certain apps and set preferred graphics processor to high-performance NVIDIA processor pre

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.

 

Looking for a particular web site ?

I remember seeing this here but i can't find it using the search thingy.

A guy posted a web site that had a comprensive list of all Windows update 32&64. I used to have it in my favorites before i formatted my HD.

Does someone know it?

They suggested a sticky for it but they never did.
