The Office Clipboard is a security threat because it stores passwords copied from password managers for a long time, so a potential attacker can see your passwords when you are not checking your computer. Even worse, this feature is enabled by default after an Office update is installed. The second inconvenience is a blinking yellow rectangle in the bottom right corner of the screen, which is disruptive during coding in Visual Studio.
Anyway, this is how to turn the feature off:
- Open Word or Excel.
- Create a new document or spreadsheet.
- Click the ↘ symbol in the Clipboard group on the Home tab.
- Click the Options button at the bottom.
- Uncheck all items.
