Hi Thomas,

A Reset won't be needed.

Please upload C:\Windows\Logs\DISM\DISM.log in your next reply.

It sounds like you're experiencing significant issues with Windows updates and driver installations. The error code 0x800700c1 typically indicates a problem with the system files or the installation media. Here are a few steps you can try before considering a full reset:

1. Run Windows Update Troubleshooter: Go to Settings > System > Troubleshoot > Other troubleshooters, and run the Windows Update troubleshooter.
2. Check System File Integrity: Open Command Prompt as an administrator and run the command sfc /scannow to check for and repair corrupted system files.
3. Use DISM Tool: If the SFC scan doesn't resolve the issue, you can use the Deployment Imaging Service and Management Tool (DISM) by running the command DISM /Online /Cleanup-Image /RestoreHealth in an elevated Command Prompt.
4. Safe Mode: Boot into Safe Mode and then try to install the updates or drivers again. This can help if there are conflicting applications or drivers.
5. Manual Installation: If the updates continue to fail, you can try downloading the specific updates or drivers manually from the Microsoft Update Catalog and installing them directly.

If none of these steps work and you're still facing issues with reinstalling Windows, it may be worth considering a full reset to start fresh. Just ensure you back up any important data before proceeding with that option.
