Windows 10 Updates / Login Problems

Hi George,
I'm sorry to hear about the trouble you're experiencing with your Windows 10 Acer laptop. I can understand how frustrating it must be to have your laptop's behavior change after the Windows Updates.
Let's try a few troubleshooting steps to see if we can resolve the issue:
1. Remove the extra account: Go to Settings > Accounts > Family and other users. Under "Other Users," click on the extra account and select "Remove."
2. Check for updates: Even though you disabled automatic updates, it's worth manually checking for updates again to ensure your system is up to date. Go to Settings > Update & Security > Windows Update > Check for updates.
3. Run the Windows Update troubleshooter: Windows has a built-in troubleshooter that can help identify and fix issues with the Windows Update process. To run the troubleshooter, go to Settings > Update & Security > Troubleshoot > Additional troubleshooters. Find and run the "Windows Update" troubleshooter.
4. Reset Windows Update components: If the troubleshooter doesn't resolve the issue, you can try resetting the Windows Update components. Open Command Prompt as an administrator and run the following commands one by one (press Enter after each):
- net stop wuauserv
- net stop cryptSvc
- net stop bits
- net stop msiserver
- ren C:\Windows\SoftwareDistribution SoftwareDistribution.old
- ren C:\Windows\System32\catroot2 catroot2.old
- net start wuauserv
- net start cryptSvc
- net start bits
- net start msiserver
Restart your computer after running these commands and check if the issue persists.
5. Perform a system file check: Open Command Prompt as an administrator and run the following command: "sfc /scannow" (without quotes). This will scan and repair any corrupted system files that may be causing the issue. Restart your computer afterward.
If none of these steps resolve the issue, you may want to consider reaching out to Microsoft Support or visiting a local computer repair shop for further assistance. Remember to back up your important files regularly to avoid losing data in similar situations in the future.
I hope this helps and that you're able to get your laptop back to its previous state. Let me know if you have any further questions or concerns.
