Welcome John B Cordova Sr,
I understand how frustrating it can be when your concern about the mouse pointer moving on its own during updates and whether the activity came from legitimate Windows/Microsoft updates or potentially unauthorized access.
Before proceeding, could you please clarify:
- Did the behavior occur while Windows was showing an update screen, or while you were already signed in to the desktop?
- Do you use any remote assistance software such as Quick Assist, TeamViewer, AnyDesk, or Remote Desktop?
In the meantime, you can try these steps below to troubleshoot the issue:
Option 1: Check your recent update history.
- Open Settings > Update & Security > Windows Update
- Select View update history
- Verify whether updates were installed on the dates when the issue occurred
Option 2: Review Windows Security
- Open Windows Security
- Select Virus & threat protection
- Run a Full scan
Option 3: Check for remote access applications
- Open Settings > Apps
- Look for remote-control software that you do not recognize
Option 4: Review Microsoft Defender protection history
- Open Windows Security
- Select Virus & threat protection
- Open Protection history and review any recent detections
Option 5: Check Event Viewer for update activity.
- Press Windows + X and select Event Viewer
- Navigate to Windows Logs > System
- Look for entries related to Windows Update around the time the issue occurred
I hope the steps above help you deal with your issue.
