Hello, Mirakesh
Welcome to Microsoft Community.
It seems like you have already taken several troubleshooting steps, but the issues persist. It's possible that some system files or settings have become corrupted or misconfigured. Here are some additional steps you can try to resolve the cursor and window tabbing issues:
- Run a full system scan with your antivirus software to ensure that there are no malware or unwanted programs causing the strange behavior. Malware can sometimes interfere with system functions and cause erratic behavior.
- Check your Windows mouse settings. Make sure you haven't enabled Inactive Scrolling and Enhanced Pointer Precision.
- Sometimes, user profile corruption can lead to strange issues. Create a new user account and see if the problems persist when using that account. If the issues disappear on the new account, you might consider moving your data to the new profile.
- Check for Background Applications: Some background applications may conflict with certain system processes. Try closing some applications running in the background to see if the issue persists. If you don't know which one might have caused the issue, perform a clean boot to try to find it out.
- Apart from updating your mouse driver, also check your graphics card driver. Graphics drivers can sometimes cause unusual behavior in the user interface. Visit the manufacturer's website for your graphics card and download the compatible driver for your system.
- If the problems started right after a specific Windows update, you can use a tool called Show or hide updates troubleshooter that allows you to hide unwanted updates from Windows Update. This can help determine if the issue is related to the update. If you are prompted that this file is not safe while downloading the tool, keep it to continue downloading.
- If you have a gaming controller connected to your PC, it may act as a mouse and keyboard and cause the cursor to move on its own. Try disconnecting your controller or disabling it in the Steam app settings.
- Disable Hardware Acceleration (Optimization for Windowed Games). In some cases, hardware acceleration in applications can cause conflicts.
If none of these steps works, consider reporting the issues you're experiencing through the Windows Feedback Hub. This allows Microsoft to gather information and potentially address the problem in future updates. To submit feedback to the developers, simultaneously press the Windows logo key and the F key on your keyboard.
Let me know if you have any other concerns.
