Office Clipboard is a security threat because it stores passwords copied from password managers for a long time, so protentional attacker can see your passwords in a moment 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 at the Clipboard group on the Home tab.
- Click the Options button at the bottom.
- Uncheck all items.
