Hi, let me help you.
If you reset to default and are still getting the same issue.
Microsoft PowerToys has a "Mouse Crosshairs" utility that draws a crosshair overlay following your pointer — if you have PowerToys installed (or it got reinstalled/enabled during the update), that's probably your "target" line, not a Windows pointer scheme issue at all.
Check for it: open PowerToys (search the Start menu), go to Mouse utilities, and look for "Mouse Crosshairs" — toggle it off. If you don't have PowerToys, search your installed apps to make sure it isn't running in the background via a startup task.
If you don't have PowerToys, the next likely culprit is gaming/peripheral software — Logitech G Hub, Razer Synapse, or similar — which sometimes adds a custom cursor or crosshair overlay as part of a "aim assist" or highlight feature. Open whichever mouse software you have installed and check its cursor/pointer settings for anything like "crosshair," "highlight," or "spotlight" and disable it.
If neither applies, it could also be Windows' own "Mouse pointer" magnifier crosshair from a remote-access or screen-annotation tool (like Zoom, Teams, or a remote desktop client) that didn't fully close — try restarting your PC, which clears any stuck overlay from a background app.
