Remove WebLogic Domain completely

My WebLogic Main directory path is: D:\Oracle\Middleware, the specific path according to the personal installation path, I now want to delete domain name is Base_domain, the specific steps are as follows:

1, delete the contents of the Base_domain domain in D:\Oracle\Middleware\wlserver_10.3\common\nodemanager\nodemanager.domains

#Domains and directories created by Configuration Wizard
#Tue Dec 11:28:34 gmt+08:00 2013
Base_domain=d\:\\oracle\\middleware\\user_projects\\domains\\base_domain
Test_domain=d\:\\oracle\\middleware\\user_projects\\domains\\test_domain

The contents of the file are roughly as above, delete the Base_domain line

2, delete the contents of the Base_domain domain in D:\Oracle\Middleware\domain-registry.xml

<?xml version= "1.0" encoding= "UTF-8"?>
<domain-registry xmlns= "Http://xmlns.oracle.com/weblogic/domain-registry" >
<domain location= "D:\Oracle\Middleware\user_projects\domains\test_domain"/>
<domain location= "D:\Oracle\Middleware\user_projects\domains\base_domain"/>
</domain-registry>

The contents of the file are roughly as above, delete the Base_domain line

3, delete D:\Oracle\Middleware\user_projects\applications under the domain directory (delete base_domain entire folder)
4, delete D:\Oracle\Middleware\user_projects\domains under the domain directory (delete base_domain entire folder)
5, delete the Start menu welogic under the domain directory (delete base_domain entire folder)
