Download from Microsoft rktools.exe. Extract this file; you will need the following two programs: srvany.exe; and instsrv.exe. READ THE INSTRUCTIONS on how these programs are used. Create a user named "magicjack", temporarily assign admin privilege. Login as “magicjack”, and install the magicjack under this profile. Install the service using the instructions you READ, and then add parameter magicjackloader.exe as the target of srvany.exe.

The following is a registry script:

Windows Registry Editor Version 5.00

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\magicJack]
"Type"=dword:00000010
"Start"=dword:00000002
"ErrorControl"=dword:00000001

5c,00,73,00,72,00,76,00,61,00,6e,00,79,00,2e,00,65,00,78,00,65,00,00,00
"DisplayName"="magicJack"

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\magicJack\Enum]
"0"="Root\\LEGACY_LINE1\\0000"
"Count"=dword:00000001
"NextInstance"=dword:00000001

[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\magicJack\Parameters]
"Application"="c:\\Documents and Settings\\magicjack\\Application Data\\mjusbsp\\magicjackloader.exe"

Reduce the “magicjack” user privilege to "user".

If you can read, follow instructions, and have at least two brain cells to rub together, then you will end up with an MJ that runs anytime the computer is on without regard to whoever is or is not logged in.
