SQL Express Batch Script: Add Account to SQL Server SysAdmin Role
Try this script and see if it adds the user account that you execute it as the sysadmin access to the SQL Server instance on your Windows machine. This will need to be saved to a .cmd or .bat file by renaming a text document and then it needs executed as a batch script.
I got this from GitHub "Script to add the current user to the sysadmin role in SQL Server" a few years back and used it for an SQL Express install to grant the sysadmin access to a local admin account on a server. I saved it after confirming it worked it worked—so I'm sharing it with others here.

::
:: CMD script to add a user to the SQL Server sysadmin role
::
:: Input: %1 specifies the instance name to be modified. Defaults to SQLEXPRESS.
:: %2 specifies the principal identity to be added (in the form "<domain>\<user>").
:: If omitted, the script will request elevation and add the current user (pre-elevation) to the sysadmin role.
:: If provided explicitly, the script is assumed to be running elevated already.
::
:: Method: 1) restart the SQL service with the '-m' option, which allows a single connection from a box admin
:: (the box admin is temporarily added to the sysadmin role with this start option)
:: 2) connect to the SQL instance and add the user to the sysadmin role
:: 3) restart the SQL service for normal connections
::
:: Output: Messages indicating success/failure.
:: Note that if elevation is done by this script, a new command process window is created: the output of this
:: window is not directly accessible to the caller.
