A family of Microsoft word processing software products for creating web, email, and print documents.
I would first use System File Checker. Find information here: https://answers.microsoft.com/en-us/windows/forum/all/sfc-scannow/bc609315-da1f-4775-812c-695b60477a93 (linked from: https://support.microsoft.com/en-us/windows/using-system-file-checker-in-windows-365e0031-36b1-6031-f804-8fd86e0ef4ca)
