Many users have claimed that after upgrading from Windows 7 or 8 to Windows 10, they are no longer able to connect three monitors.
suggested the following fix: Connect all monitors and proceed to Control panel > Display > Change display settings in the Control panel. All three screens should be visible there. If one of the screens appears to be unconnected (the screen is a darker color than the others), right-click it and select Extend desktop to this monitor. (You may need to restart your computer after plugging in all three monitors before trying this.)
There are far too many alerts.
At times, Windows 10 might be a little too notification-heavy. If these pop-ups are interfering with your workflow, go to Start > Settings > System > Notifications & actions and modify them. There, you can turn on or off which notifications you desire.
The mouse pointer begins to move on its own.
Your Windows 10 laptop or desktop pointer will occasionally start moving on its own, causing you to lose focus while working or browsing. Microsoft has provided a couple of possible solutions.
Run the hardware troubleshooter to see if there are any issues. Select Control Panel by pressing Windows + X. Go to Troubleshooting and select View all things from the left panel. Follow the instructions for the Hardware and Devices troubleshooter.
Drivers for the mouse and other pointing devices should be updated. Press Windows + R, type devmgmt.MSC, and then press Enter. Expand Mice and other pointing device drivers. Right-click on the driver of your mouse, and click update.
