By default, AutoCorrect mode is enabled in the Microsoft Word text editor and Microsoft Excel spreadsheets, which corrects some common user errors: two uppercase letters at the beginning of a word, Caps Lock enabled, and others. Not everyone likes this service, and if you want, you can quickly turn it off.
Instructions
Step 1
To turn off AutoCorrect, click on the File menu and select the Options menu item.
Step 2
You will see a dialog box in which you should select the "Spelling" section and click the "AutoCorrect Options" button.
Step 3
In the new window, you can make all the necessary settings and set the autocorrect parameters you need, as well as completely disable everything that interferes with your work.
