Hi there,
I understand that you are experiencing a crashing issue when accessing the "Accounts" section in Windows Settings on your Windows Server 2019 Essentials. Based on the error message you provided, the fault seems to be related to the usercpl.dll module.
Here are a few suggestions you can try to troubleshoot the issue:
1. Update Windows: Make sure your server is up to date with the latest Windows updates. Sometimes, Microsoft releases patches to fix such issues.
2. Run DISM tool: Open Command Prompt as an administrator, then run the following command: `DISM.exe /Online /Cleanup-image /Restorehealth`. This command will scan your system for any corruption and attempt to repair it.
3. Perform a clean boot: Sometimes, third-party software conflicts can cause crashes. Perform a clean boot to start Windows with only the necessary system services and disable all non-Microsoft startup items. This will help identify if any third-party software is causing the issue.
4. Re-register usercpl.dll: Open Command Prompt as an administrator and run the following command: `regsvr32 C:\Windows\System32\usercpl.dll`. This command will re-register the usercpl.dll module, which might resolve any issues.
5. Check for malware: Use a reliable antivirus program to scan your server for any potential malware. Malware can sometimes cause system instability.
If none of the above steps resolve the issue, you may want to consider reaching out to Microsoft support for further assistance. They have dedicated resources to help with Windows Server-related issues.
Keep in mind that, as a home user, Windows Server 2019 Essentials might not be the best choice for your needs. It is designed for small businesses with limited IT support. You might want to consider using Windows 10 or another more user-friendly operating system for your movie/file server.
I hope this helps! Let me know if you have any further questions.
