Microsoft office setup can look cumbersome but actually, it is very simple if you follow the right process. I myself rely only on one website office.com/setup. If you want to get started with your Microsoft account in no time, you must also visit this website.
Simply, sign in to your account
Add the product key
Finally, select the apps you want to use and you are done.
In case you have queries, feel free to revert and we will get back to you.
