I accidently uninstalled the cumulative updates for windows 10. What do I do?
Just go to settings, Update and security, click on check for updates.
Do you mean that you uninstalled the 1909 feature release or that you uninstalled the May security updates for 1909?
Just perform a Repair Installation.
A Repair Installation allows you to keep the programs and data though redundant backups are always a good idea. This is not the same a Clean Install.
