cmdhere on win7

Shift + right-click shows a context menu with additional entries such as Open command window here.

To add Open powershell here with and without elevated privileges:

1. Windows Registry Editor Version 5.00
2. [HKEY_CLASSES_ROOT\Directory\shell\ps]
3. @="Open powershell here"
4. [HKEY_CLASSES_ROOT\Directory\shell\ps\command]
5. @="C:\\windows\\system32\\WindowsPowerShell\\v1.0\\powershell.exe -NoExit -Command Set-Location -LiteralPath '%L'"
6. [HKEY_CLASSES_ROOT\Directory\shell\Runas]
7. @="Open admin powershell here"
8. [HKEY_CLASSES_ROOT\Directory\shell\Runas\Command]
9. @="C:\\windows\\system32\\WindowsPowerShell\\v1.0\\powershell.exe -NoExit -Command Set-Location -LiteralPath '%L'"
10. [HKEY_CLASSES_ROOT\Drive\shell\ps]
11. @="Open powershell here"
12. [HKEY_CLASSES_ROOT\Drive\shell\ps\command]
13. @="C:\\windows\\system32\\WindowsPowerShell\\v1.0\\powershell.exe -NoExit -Command Set-Location -LiteralPath '%L'"
14. [HKEY_CLASSES_ROOT\Drive\shell\runas]
15. @="Open powershell admin here"
16. [HKEY_CLASSES_ROOT\Drive\shell\runas\command]
17. @="C:\\windows\\system32\\WindowsPowerShell\\v1.0\\powershell.exe -NoExit -Command Set-Location -LiteralPath '%L'"

Keys having runas in their names are the ones that will trigger elevated privileges. So yes, it seems we can only map one elevated command per HKEY_CLASSES_ROOT key...
