Since the mouse works normally on the restart screen and in a newly created Windows account, this is most likely caused by a user-specific setting, startup application, or corrupted profile rather than the mouse hardware or driver.
In the affected account, please try:
- Open Task Manager > Startup apps, disable all non-Microsoft items, then restart.
- Temporarily uninstall or disable mouse, gaming, overlay, and customization software such as Logitech/Razer utilities, Xbox Game Bar, Discord overlay, MSI Afterburner, or screen-recording tools.
- Go to Settings > Bluetooth & devices > Mouse > Additional mouse settings > Pointer Options, disable Enhance pointer precision, and test again.
- If the issue remains, back up your personal files and move to the new Windows account where the mouse works correctly. This may be faster and more reliable than continuing to repair the damaged user profile.
There is no need to replace the mouse or reinstall its driver again, since the same hardware works correctly under another account.
Hope this helps. Have a nice day
