Hello! Abby. Thank you for the details. I'm glad to assist you with this.
Windows sometimes hides these folders by default:
Open File Explorer.
Click View → Show → Hidden items.
Then go to Options → View tab.
Uncheck “Hide protected operating system files (Recommended)” — it will warn you, click Yes.
Now look again in C:.
If the Windows folder now shows up, it was just hidden.
See if this helps. If you need further assistance, just let me know.
Best regards,
Kimberly
