Hi, @Nedra Larry
Thank you for posting in Microsoft Q&A forum.
One possible workaround is to try rolling back the update to a previous version. To do this, go to Settings > Update & Security > Windows Update > View update history > Uninstall updates. Find the Realtek-extension update and select Uninstall.
Another workaround is to try updating the drivers for your wireless mouse. You can do this by going to Device Manager, finding your mouse under Mice and other pointing devices, right-clicking on it, and selecting Update driver.
If these workarounds do not solve the issue, you may need to contact Microsoft support for further assistance.
