Hi there and welcome
You are best to do the setup again, so return it to a as new condition.
To do this, on the sign in screen, where you enter the password, you see a power icon (a circle with a line through it)
Hold the left SHIFT key on the keyboard, and click the power icon and click restart.
Keep shift held, until it has restarted and you are at a menu then release.
Click on Troubleshoot, then Reset My PC
Choose to delete all your files.
Let this complete and when it has, the Acer is brand new again and you can do the setup all over
If you have continued problems, or would like any additional information or assistance, please do not hesitate to let me know.
Else if you can take a second to rate my service by clicking one of the stars at the top of the screen then submit, that would be greatly appreciated.
