My Cursor disappears when writing in Word, editor or any Office program.

Yes this is a common Windows issue and it’s usually easy to fix.

First, turn off the text cursor indicator. Go to Settings to Accessibility to Text cursor and disable it. This alone fixes the problem for many people.

Next open Word or any Office app go to File then go  Options to Advanced and turn on Disable hardware graphics acceleration then restart the app.

Also check Settings to Accessibility to Mouse pointer and touch and reset the cursor to the default size and color.

If the problem continues update your graphics driver. If it started after an update rolling back the driver can help.

This is a display issue in Windows not a mouse or Word problem.
