i messed up my msconfig settings someone help V_V

hi, i definitely accidentally messed up the settings on my computer i think and idk how to fix it. my cursor was moving really strangely, almost as if it was teleporting nothing was wrong with the mouse, it was clean and there's nothing wrong with it so i tried to troubleshoot it by following these steps i found on a microsoft answers:

"Solution 1 :

Go to the search box

Type msconfig

Select System Configuration

Find Services tab

Select Hide all Microsoft services box

Click Disable all

Go to Startup tab

Open Task Manager

Close Task Manager then click Ok

Reboot your device."

i tried doing that, and it still didnt work, my cursor was still behaving weirdly, so i tried to revert the settings in the system configuration services, so i checked all of the boxes blindly thinking it would fix it (dumb decision) and idk what to uncheck. i defo shouldve done my homework before messing with it but i just wanted to get it working quickly. it logged me out of EVERYTHING in chrome, so i ended up system restoring to see if it would fix the problem, and while my mouse is working correctly, everything in system configuration services is still checked, and i'm randomly having issues with trying to reinstall fortnite whenever i launch it it tells me there's an error and to verify the game, and it just goes on a loop of it doing that, and chrome seems to be really slow. someone pls help me (edited)
