Windows 10: intermittent lag on left click on icon to open programme

Hello, I've had this almost from installation of Win 11. Usually, left click works fine, but sometimes nothing happens for a while, then, if you've clicked more than once, there is a rush of multiple windows opening. I've run sfc/ scannow, I've done all the suggested things for mouse adjustment - whatever it is, it's intermittent. Any ideas?

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.

 

Intermittent UI lag - Windows 10 21H1

Problematic files are photos and videos at this point in time. I use VLC for videos, and Windows Photo Viewer for images.
I launch all these directly and manually from File Explorer only - I don't use any third party media organizers.

Interestingly enough, mngerholds suggestion of using Procmon has unveiled that when lag does happen, there is a large influx of UDP and NetBIOS entries via SVCHOST -- but I'm yet to narrow down what the trigger condition is...

When there is no lag, UDP and NetBios entries are not present.

Here is a healthy launch of a file:




Here is a laggy launch.

 

Icons move to left

Hi,

One of the possible causes why the icons on your desktop are being automatically rearranged is because the Auto arrange icons option is enabled. To address this concern, we suggest disabling the Auto arrange icons option. Follow these steps to do so:

• Right-click on your desktop.
• Click View.
• Click on Auto arrange icons to disable it. Make sure that the Auto arrange icons option is unchecked.
  
  
  
  
  

If the same issue persists, it will be best to delete the IconCache file. These steps will help you delete the IconCache file:

• Press the Windows key + R.
• On the Run dialog box, type %userprofile% and then hit the Enter key.
• A file Explorer window will pop up and it will open your user profile folder. Click on the View tab and then check the box beside Hidden items. This will let you see the hidden items in the folder.
  
  
  
  
  
• Open the AppData folder and then open the Local folder.
• Look for IconCache file and then delete it.

Let us know if further assistance is needed.
