When using Windows Server 2016, the built-in administrator is not able to open Microsoft Edge and the following error message is displayed. This error is annoying since some software installation requires to click on a link to download additional software or documentation related.
Microsoft Edge can’t be opened using the Built-in Administrator account. Sign in with a different account and try again.
In order to reproduce the issue is really easy, just try to open Microsoft Edge on Windows Server 2016 and the following message will be displayed.
How to fix it?
There are a couple of ways, registry, changing the local settings and Group Policies. My recommendation is always to use Group Policy if we are using in a domain environment, and the configuration location on the GPO is the same path that we are going to use to fix changing the local settings.
Open gpedit.msc as administrator or from a command prompt that had been opened with administrator. Expand Computer Configuration, Windows Settings, Security Settings, Local Policies, and then click on Security Options. Then, double click on User Account Control: Admin Approval Mode for the Built-in Administrator account.
In the new window, make sure to select enable, and since we are changing the local settings a restart of the server is required to refresh the settings.
After restarting the server, the Microsoft Edge will be available to the built-in administrator.
