erratic behavior

About this tag
Erratic behavior in Windows often manifests as unpredictable mouse pointer movement, random program shutdowns, and unresponsive input devices. Users have reported issues such as the mouse cursor wandering across the screen, stuttering, or becoming completely unusable, particularly after system repairs or driver updates. These problems can occur with both wired and wireless peripherals, and may persist even after installing official drivers from Microsoft.

Troubleshooting steps typically involve checking for updated drivers, performing clean boots, or running system file checker scans to restore stability.
