軟件注冊是商業軟件必不可少的模塊，在整個程序中啟到舉足輕重的作用。
系統啟動時首先會檢測程序是否注冊，如果程序沒有注冊可以使用30次，試用次數完成後將彈出注冊界面。程序每次登陸都會將程序使用次數寫入到注冊表中，程序注冊是也會將注冊碼已加密的方式寫入到注冊表中。
public static void RegMetod(bool isDownLoad)
{
try
{
SoftReg softReg = new SoftReg();
//判斷軟件是否注冊
RegistryKey retkey = Registry.CurrentUser.OpenSubKey("SOFTWARE", true).CreateSubKey(Encrypt.EncryptDES("mySoftWare", Const.EncryptKey)).CreateSubKey(Encrypt.EncryptDES("Register.INI", Const.EncryptKey));
foreach (string strRNum in retkey.GetSubKeyNames())
{
if (Encrypt.DecryptDES(strRNum, Const.EncryptKey) == softReg.GetRNum())
{
run(isDownLoad, "正式版", "");
return;

Registry.SetValue("HKEY_LOCAL_MACHINE\\SOFTWARE\\" + Encrypt.EncryptDES("mySoftWare", Const.EncryptKey), "UseTimes", tTimes);

完成以上即可實現軟件注冊！
ROOT之後就可以獲取最高權限，舉個例子:你買了手機沒有ROOT限權只能玩些基本應用，如果你想把手機上不需要的系統軟件刪掉，比如系統自帶的舊版本UC，你是刪不掉的。如果你有ROOT權限，你就可以把它刪掉。系統為了保護這些功能的使用正常，（怕誤刪除）一般的官方系統是未ROOT的，但是有些軟件是需要ROOT的，如果你想更改系統的字體啊，第二屏動畫呀，修改某些系統設定呀。都是需要ROOT的，但是不能亂來的。簡單點就是：就是獲得管理員權限 你可以任意得改動系統文件 你在系統中擁有了絕對的權利 許多系統優化應用需要ROOT權限。關於安卓系統方面的知識你可以去機鋒論壇上多了解了解。
一般的CMS都有這個模塊，單獨的系統倒是沒有
