Vista - Cannot Open Control Panel (Fixed)

World of Warcraft was giving me headache yesterday. FPS near Ogri'la was only 4fps, although lag was not too bad (~150-200ms). So I decided to disable addons, defrag HD blah blah. I was also using procmon from sysinternals to see if there was anything hogging Vista...

I noticed SearchIndexer was a bit troublesome and stopped the service. While there, I went thru the list and disabled a couple of other that did not seem useful/applicable. One of them was "Software Licensing".

Software Licensing Service Description:
Enables the download, installation and enforcement of digital licenses for Windows and Windows applications. If the service is disabled, the operating system and licensed applications may run in a reduced function mode.

Apparently, if you disable this service you cannot open Control Panel. It looks like it's coming up but then disappears immediately. Enabling/starting service fixes the issue...
