There is a addon reg entry to give you Admin access "Takeownership" via right click mouse.
that is the easyiest way I know.
Take Ownership Shortcut
You have to disable UAC before you install.
----------------------------------------------
Windows Registry Editor Version 5.00
[HKEY_CLASSES_ROOT\*\shell\runas]
@="Take Ownership"
"NoWorkingDirectory"=""
[HKEY_CLASSES_ROOT\*\shell\runas\command]
@="cmd.exe /c takeown /f \"%1\" && icacls \"%1\" /grant administrators:F"
"IsolatedCommand"="cmd.exe /c takeown /f \"%1\" && icacls \"%1\" /grant administrators:F"
------------------------------------------------------
add via reg entry. This is what I use.
