Why my shortcut key for Bold option automatically change from 'Ctrl+B' to 'Ctrl+ N'? (Word for Windows)

Unfortunatelly it is not the best solution.

1. The bold shortcut is not only one shortcut which is changed.
2. Sometimes Word back to "standard" wrong shortcuts

Microsfot technical support told me that it is somethiong wrong with Wor files and I have to remove oiffice manualy (incluiding registry cleaning) and install again. Adter that, shortcuts had back to standard (proper one), unfortunatelly only for two weeks. After that issue come back :-/

Thank you.

This is so anoying! Been using these short cuts forever! I really hope Microsoft change this back ASAP. The whole office is complaining!

And always used CTRL+ N to make a new document. What is this short cut now then?
