So I really need to access some things that only the system account has access to in this case the \System Volume Information.

First off lets download PSExec which is a part of PSTools from Microsoft Sysinternals. Unpack the PSTools.zip. Then run psexec /D /I /S cmd.exe. A new windows should pop up.

Microsoft Windows [Version 6.2.9200]

C:\Windows\system32>whoami
nt authority\system

So what does the /D /I /S stand for. Well /D tells psexec not to wait until the process is done prior to returning. /I is that the new program is to interact with a session on the computer. /S is for run as system.

In case you are running an really old system you might use the AT command to execute a cmd to interact with the desktop and under the system account.
