Add something to your Windows 7 registry with a file with the .reg file extension.

You could just double-click on YOURNAMEHERE.reg to make it run. There will be stuff inside like this:

Windows Registry Editor Version 5.00
 
[HKEY_LOCAL_MACHINE\SOFTWARE\Foo]
 
[HKEY_LOCAL_MACHINE\SOFTWARE\Foo\Bar]
 
[HKEY_LOCAL_MACHINE\SOFTWARE\Foo\Bar\Baz]
 
[HKEY_LOCAL_MACHINE\SOFTWARE\Foo\Bar\Baz\Qux]
"AuditLevel"="0"
"AuditQueuePath"=".\\Private$\\auditqueue"
"ConnectionString"="use your imagination..."
