Hi Ed Embardo,
If your Windows 7 PC still has the manufacturer's recovery partition, you may be able to restore it to its original factory state by pressing the recovery key during startup (a vendor-specific key). The exact method depends on the computer manufacturer as mentioned by the other user in this thread.
Before proceeding, make sure to back up any personal files, as a factory recovery will typically remove installed programs, settings, and personal data.
If the recovery partition is no longer available, you would need the manufacturer's recovery media or a Windows installation disc to perform a clean installation.
Important: Windows 7 reached end of support on January 14, 2020. As a result, it no longer receives security updates from Microsoft. After recovery, consider upgrading to a supported version of Windows if your hardware is eligible.
I hope this helps point you in the right direction. Let me know if you need further assistance, feel free to ask me by clicking "Add Comment" or "Add Answer" if you cannot add comment so your response will be visible. Thanks for your effort.
