I think I have two accounts and I only want one for everything. how do I do it?

if it an android you just need tologininto your gmail account on a regular computer your stuff should be saved especially your email and files should be stored in google drive

I don't know what account you are talking about but start by making sure your caps key is off and remember the password is case sensitive. If you are still having trouble you will have to contact the administrator.

You would be talking about opening a Google account.

You may already have one from the Android tablet. It will work just the same. Then when signed in go to the Google Play site, and shop.

Bear in mind that Android apps may not work on Windows, but there will often be a Windows version.

Point your web browser at One account All of Google

If another account comes up, sign out of it by clicking the avatar in the upper-right then clicking "Sign out."

If you then still can't sign in to your account, click the "Need help?" link on the sign-in page.

You will have to use the password recovery of Google to get your password and you will have to answer security questions to get it. Otherwise you are out of luck. The reason for this is so hackers don't get into your account.

If you suspect that someone else knows or has changed your password, please reset it so nobody else can sign in to your account. To do so, just enter your username on the password-assistance page.
Account username:

• For Google Accounts without Gmail: the full email address you used to create your account.
• For Google Accounts with Gmail: everything before '@gmail.com'

If you think someone has access to the email address associated with your Google Account, please change the password for your email as well. Learn more about keeping your account secure.
If you're unable to reset your Google Account password, and you can't sign in to your account, you can fill out the account recovery form.

Click the "Need help?" link on the Google sign-in page.
