Using the runas command in Windows 10 to run a command as admin.

The runas command in Windows 7 8 and now Windows 10 allows the unprivileged user to execute a command as a superuser. This is rather like the sudo command for Linux and UNIX. In the example below, I am executing a command on the computer BLUFOR as the user Dobbo. I am running notepad as an example.

C:\Users\mike>runas /user:BLUFOR\Dobbo notepad
Enter the password for BLUFOR\Dobbo:
Attempting to start notepad as user "BLUFOR\Dobbo" ...

You may also open a Powershell window as the administrator.

C:\Users\mike>runas /user:BLUFOR\Dobbo powershell
Enter the password for BLUFOR\Dobbo:
Attempting to start powershell as user "BLUFOR\Dobbo" ...

This is the help for the runas command. This shows the many command line parameters that may be applied to this command.

C:\Users\mike>runas /?
RUNAS [ [/noprofile | /profile] [/env] [/savecred | /netonly] ]
        /user:<UserName> program
RUNAS [ [/noprofile | /profile] [/env] [/savecred] ]
        /smartcard [/user:<UserName>] program
RUNAS /trustlevel:<TrustLevel> program
   /noprofile        specifies that the user's profile should not be loaded.
                     This causes the application to load more quickly, but
                     can cause some applications to malfunction.
   /profile          specifies that the user's profile should be loaded.
                     This is the default.
   /env              to use current environment instead of user's.
   /netonly          use if the credentials specified are for remote
                     access only.
   /savecred         to use credentials previously saved by the user.
   /smartcard        use if the credentials are to be supplied from a
   /user             <UserName> should be in form [email protected] or DOMAIN\USER
   /showtrustlevels  displays the trust levels that can be used as arguments
                     to /trustlevel.
   /trustlevel       <Level> should be one of levels enumerated
                     in /showtrustlevels.
   program         command line for EXE.  See below for examples
> runas /noprofile /user:mymachine\administrator cmd
> runas /profile /env /user:mydomain\admin "mmc %windir%\system32\dsa.msc"
> runas /env /user:[email protected] "notepad \"my file.txt\""
NOTE:  Enter user's password only when prompted.
NOTE:  /profile is not compatible with /netonly.
NOTE:  /savecred is not compatible with /smartcard.

I cannot run the dir command with the runas command. But this is very useful for running various commands as the administrator. Much more information on this command here:
