A family of Microsoft word processing software products for creating web, email, and print documents.
Do you see some version of Office or Microsoft 365 listed in Installed Apps in Windows Settings? One-time purchase licenses include the word "Office," for example, Office Home & Business 2024, while subscription versions are called Microsoft 365 en-us (for example). If you find an installed product, try repairing it.
You can also search for the individual apps from the Windows Start menu. Are you able to start them from there?
If it turns out the the Office apps are actually missing, how did you install them originally? Typically, you should see your Office product listed in your associated account, as Dave has already suggested.
