Hi! Csaba. I'm here to help.
This actually can stem from either hardware or software/Windows settings. Here’s a structured way to troubleshoot it:
1. Rule Out Hardware Issues
Test another mouse (wired or wireless) to see if the issue persists.
Change the USB port (try both USB 2.0 and 3.0).
If wireless, check battery or receiver interference.
Clean the mouse buttons — dirt can cause contacts to fail intermittently.
2. Check Windows Mouse Settings
Double-click speed may be too high or too low.
Go to:
Settings → Bluetooth & devices → Mouse → Additional mouse settings
→ Buttons tab → Double-click speed.
Adjust the slider more toward the middle.
ClickLock (sticky click) might be interfering:
Same menu → ClickLock → make sure it’s off.
3. Look at Windows 11/Explorer Issues
Some users report that File Explorer or the Start Menu occasionally “loses focus,” making the first click only set focus rather than execute.
Try clicking slowly and see if the first click just highlights but doesn’t activate.
Restart Windows Explorer:
Ctrl + Shift + Esc → Task Manager → Windows Explorer → Restart.
Check if it’s app-specific (e.g., only in File Explorer, browsers, or across the whole system).
4. Display / Input Lag
High system load or driver issues can cause missed clicks.
Update:
Mouse/Touchpad drivers (from manufacturer).
Graphics drivers (NVIDIA/AMD/Intel).
Try disabling pointer precision:
Mouse properties → Pointer Options → Enhance pointer precision → Off.
5. Advanced Fixes
Check for background software:
Some overlay or “helper” apps (like screen recorders, RGB apps, even some antivirus UI overlays) can intercept clicks.
Run SFC/DISM in case system files are glitching:
sfc /scannow
DISM /Online /Cleanup-Image /RestoreHealth
If it only happens in desktop icons:
Check Folder Options → Single-click to open item (make sure it’s set to Double-click if you prefer normal behavior).
Note: You can skip the steps that you've done already.
Please let me know how it would go.
Best regards,
Kimberly
