If you want to uninstall it, go to Control Panel>Programs and Features, look for the version of MS Office that is installed, and click that. Then you should be able to uninstall individual components.
I use Windows 10 within which is packed "OneNote" which among other things offers the opportunity to scan, select, paste and edit via OCR. I know it works because when I first used it a day ago I scanned the page of a book and carried out certain actions which regrettably I did not note the end result of which was a near perfect copy.
Since then try as hard as I have I have not been able to make it work.
So, can anyone offer me any guidance?
