Default Google Account Not Changing In Windows 10 FIX.
After updates by Google, Chrome has now lost the ability to manually change the default account. Before this update, users were able to change their default Gmail account easily by signing out of the current default account. The previously signed in number two accounts automatically became the default account. However, after an update by Google, the only method to change your default Google account is by signing out of all logged-in Google accounts.
It is very easy to change the default Google Account for Google Calendar, Gmail, and other Google services. It’s especially useful if you use multiple Google Accounts in the Chrome browser.
It’s also easy to switch between Google accounts in the Chrome browser. But if you use one account more frequently than others, you may want to change your default Google account to that one.
How to Change Default Google Account
The trick to setting the default Google account in Chrome is understanding how the default account is selected in the first place. There isn’t some setting buried in your Google account that lets you select this. Instead, Google uses the initial account you used to log in as the “default” Google account.
