[TYPO3-english] How to remove an extension in Required state (Rq)?

[PIT Solutions]

Hi,	Does anybody know how to remove an extension in Required state (Rq)? When I go to "Information" view from "Loaded Extensions" by clicking on the extension it's said that "This extension is entered in the TYPO3_CONF_VARS['SYS']['requiredExt'] list and is therefore always loaded." and no "remove the extension" option is available under the "Current status:". Also I couldn't find the "TYPO3_CONF_VARS['SYS']['requiredExt']" in typo3conf/localconf.php. I searched in some files in typo3/sysext folder as the extension which I want to remove is a system extension and also checked Install configuration at the 'Admin Tools' module but couldn't find it. I'm using typo3 4.4.7. Regards,	Sankar.V
