Troubleshooting Windows installation is a crucial part of ensuring the reliability and integrity of an organization’s IT infrastructure. Here are some steps to follow:
Pre-Installation Checklist
- Verify system requirements: Ensure that the target computer meets the minimum system requirements for the operating system and applications required.
- Backup critical data: Back up important files, such as configuration files and user data, to a secure location in case of installation failures or data loss.
- Test internet connectivity: Verify that the internet connection is stable and functioning properly.
Step 1: Installation Failure
- Check event logs: Review event logs for any errors or warnings related to the installation process.
- Run system files check (sfc /scannow): Run this command on a command prompt or PowerShell window to scan and repair corrupted system files.

- Run DISM (Deployment Image Servicing and Management) tool: Use the
dism.execommand to scan for and repair corruption in the Windows installation media or network location.
Step 3: Application Installation
- Check application dependencies: Verify that all dependent applications are installed correctly and functioning properly.
- Try a different application: If possible, try installing one of the dependent applications first.
Step 4: Networking Issues
- Verify DNS settings: Ensure that DNS (Domain Name System) is configured correctly.
- Check network cables: Inspect network cables for any damage or issues.
- Run Network Troubleshooter: Use the Windows built-in Network Troubleshooter to diagnose and resolve network connectivity issues.
Step 5: User Account Issues
- Verify user account credentials: Ensure that the login credentials are correct for all users.
- Check user accounts in Active Directory: Verify that the user accounts in Active Directory (AD) are correctly configured and synchronized.
- Try a different user account: If possible, try logging on with a different user account.
Post-Installation Check
- Verify installation success: Confirm that the installation was successful by checking for errors or warnings in event logs.
- Run Windows Update: Run Windows Update to ensure that all updates are installed correctly.
By following these steps, you can troubleshoot and resolve common issues related to Windows installations, ensuring a smooth and reliable IT service level agreement (SLA).
