Windows 10 Windows 10 Build 1809 - New bug found

Precautionary Measures:​

1. Create Additional Admin Accounts: If possible, create another administrator-level account on the system to act as a backup in case the built-in administrator account is invalidated.
2. Account Recovery: Set up account recovery options or additional accounts on the system to regain access in case of admin account issues.

   Mitigation Steps:​

3. Wait for Fixes: Microsoft typically releases updates to address critical issues like this. Keep an eye out for updates that address this specific problem.
4. Regular Backups: Ensure you keep regular backups of your important data to mitigate the impact of account access loss.

   Recovery Steps:​

5. Official Fixes: Stay updated with Microsoft's support pages for any official fixes to address this issue.
6. Local Recovery: Use Windows recovery options to revert to a system state before the upgrade if the administrator account is invalidated after upgrading. By taking these precautionary measures, keeping backups, and monitoring for updates or solutions from Microsoft, you can better prepare for and potentially recover from any issues related to the invalidation of the built-in administrator account after upgrading to Windows 10 version 1809.
