GPRESULT is the right command, but it cannot be run without parameters. /v or verbose option is difficult to manage without also outputting to a text file. E.G. I recommend using
gpresult /user myAccount /v > C:\dev\me.txt–Ensure C:\Dev\me.txt exists
Another option is to display summary information only which may be entirely visible in the command window:
gpresult /user myAccount /r
The accounts are listed under the heading:
The user is a part of the following security groups
