How do I modify user groups in Windows 8?

Solution 1:

Use the command 'net localgroup' as follows. This works on non-Pro Win 8 as well.

1. Open a privileged command prompt: Open Explorer and search for 'cmd.exe'. When it appears in the file list, right-click and select 'Run as Administrator'.

2. Run the command: In the privileged command prompt window, enter the command as follows:

   net localgroup [groupname] [username] /add
   

   To see a list of local groups available, just type:

   net localgroup
   

   To see other options, type:

   net help localgroup
   

Solution 2:

Type lusrmgr.msc in "RUN" dialogue box which is accessible via shortcut key combination WinKey + R.

I must mention I'm not sure if it works in non "Pro" versions of windows 8. you can try it any way...
