Windows 10: Windows 11 UI lag breaks basic keyboard shortcut

This regards the windows key+number keyboard shortcut the one windows 7 introduced that made alt+tab mostly obsolete. In windows 7-10, if you had 2 or more windows of a program open, you could quickly hit winkey+# to switch to the first window of that application. When you pressed it, it would show thumbnails for the windows of that application, and when you released the number key it would select the one you had highlighted. However, Windows 11 lags when opening the thumbnails and the UI breaks. If you hit win+# and don't wait for it to slowly load the thumbnails and you just release the nu

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.

 

Lag when using shortcut (keyboard) keys

Update, as of 12/5/15

--- revised 2/18/16 --- No further instances of lag (which can also stop macros from completing) since SUPERFETCH was disabled. However, some users report occasional lag despite this measure, and
the underlying problem is extant.

It appears to have nothing to do with hardware, keyboard drivers, SFC or services other than SF.

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.
