<p>When you add or remove users from a domain security group, users have to logoff/login again or restart their computer. This can be frustrating, but luckily there is a solution to update group membership without a restart.</p>
<p>Open Command Prompt <strong>CMD</strong> and type the following commands:</p>
<p><strong>taskkill.exe /F /IM explorer.exe</strong></p>
<p>This will kill the <strong>explorer.exe</strong> process. Now we have to start Windows Explorer again.</p>
<p>runas<strong> /user:%USERDOMAIN%\%USERNAME% explorer.exe</strong></p>
<p>Replace <strong>%USERDOMAIN%\%USERNAME%</strong> with your credentials. Once done, you will have to enter the password for that user account. After you enter the password the system will get a new token for you and thus update your group membership.</p>
<p>Hope this helps.</p>
