Mouse cursor missing on fourth monitor after Windows 26058.1100 ge_release update

If your mouse cursor is mysteriously vanishing on one of your multi-monitors in Windows 10, here are some steps you can try to resolve the issue:

1. **Check Monitor Connections**:
- Ensure that all your monitor cables are securely connected to your computer. Sometimes a loose connection can cause display issues.

2. **Disconnect the Second Display**:
- If you're using a dual monitor setup, try disconnecting the second display temporarily. Reconnect it after a moment and see if the mouse cursor reappears. Sometimes this simple action can reset the display configuration and resolve the issue².

3. **Adjust Mouse Settings**:
- Open the **Mouse Properties**:
- Click the **Start** button, type "mouse," and then click **Mouse**.
- Go to the **Pointer Options** tab:
- Under **Visibility**, select the **Display pointer trails** check box.
- Move the slider towards the extreme left so that the trails are the shortest.
- Apply the changes.
- Check if the mouse cursor becomes visible again¹.

4. **Update Graphics Card Drivers**:
- Sometimes display issues are related to outdated or corrupted graphics card drivers.
- Uninstall the current graphics card driver:
1. Click **Start**, then **Control Panel**, and double-click **System**.
2. Click the **Hardware** tab, and then click **Device Manager**.
3. Under **Display adapters**, double-click the entry for your graphics card, and then click the **Driver** tab.
4. Click **Uninstall** and follow the uninstallation wizard.
- Visit the manufacturer's website for your graphics card and download and install the latest driver update.
- Reboot your computer and check if the mouse cursor issue is resolved¹.

5. **Toggle the Magnifier** (for Windows 11/10):
- Press **Windows key + Plus key** to turn on the Magnifier.
- To turn it off, press **Windows key + Esc key**³.

6. **Ctrl + Alt + Del Trick**:
- Press **Ctrl + Alt + Del** to bring up the security options screen.
- Some users have reported that this action forces the mouse cursor to appear on the screen, especially if you have multiple monitors and can't locate the cursor because it's on another screen⁴.

Remember to try these steps one by one and check if the mouse cursor reappears after each action. Hopefully, one of these solutions will help you regain your elusive cursor! :computer_mouse:️
