Windows 10: Cannot add office account to my system

I recently reset my system and at start-up when I try to add my Microsoft office account, It gives me a message that this account does not exist. How can i get around this?

Remove account

I suggest you backup your personalized files first before removing the account.
To delete an account, follow these steps:

1. Press WIN + X keys and click Command Prompt (Admin) from the menu.
2. Type the following command and press Enter. Replace test with the name of your sister's account. Code:

 

Office And Light Gaming Build

There's nothing wrong with the build, but I have some suggestions to, IMHO, make it better:

• You list a 550 watt PSU, but you have a 51 watt CPU and a GPU that pulls 120 watts at the max. In other words, your system will pull under 200 watts at maximum load, which it sounds like will be rarely. PSU's are most efficient between 50-80%, and even at max load, this system won't reach 50%. Suggest a PSU 400 watts or less, like the Seasonic G-360.
• RAM's really cheap. Suggest getting 16 GB instead.
