为防止有的光盘带有病毒，自动运行时就感染到电脑上了。我们可以设置禁止CD-ROM的自动运行以提高系统的安全性。
方法一
1、新建一个文本文档。
2、将下列代码拷到文本文件中。WindowsRegistryEditorVe筠续师诈rsion5.00[HKEY_LOCAL_MACHIN呶蓟鹭毵E\SYSTEM\CurrentControlSet\Services\Cdrom]"DependOnGroup"=hex(7):53,00,43,00,53,00,49,00,20,00,6d,00,69,00,6e,00,69,00,\70,00,6f,00,72,00,74,00,00,00,00,00"ErrorControl"=dword:00000001"Group"="SCSICDROMClass""Start"=dword:00000001"Tag"=dword:00000002"Type"=dword:00000001"DisplayName"="CD-ROMDriver""ImagePath"=hex(2):53,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,44,00,\52,00,49,00,56,00,45,00,52,00,53,00,5c,00,63,00,64,00,72,00,6f,00,6d,00,2e,\00,73,00,79,00,73,00,00,00"AutoRun"=dword:00000000"AutoRunAlwaysDisable"=hex(7):4e,00,45,00,43,00,20,00,20,00,20,00,20,00,20,00,\4d,00,42,00,52,00,2d,00,37,00,20,00,20,00,20,00,00,00,4e,00,45,00,43,00,20,\00,20,00,20,00,20,00,20,00,4d,00,42,00,52,00,2d,00,37,00,2e,00,34,00,20,00,\00,00,50,00,49,00,4f,00,4e,00,45,00,45,00,52,00,20,00,43,00,48,00,41,00,4e,\00,47,00,52,00,20,00,44,00,52,00,4d,00,2d,00,31,00,38,00,30,00,34,00,58,00,\00,00,50,00,49,00,4f,00,4e,00,45,00,45,00,52,00,20,00,43,00,44,00,2d,00,52,\00,4f,00,4d,00,20,00,44,00,52,00,4d,00,2d,00,36,00,33,00,32,00,34,00,58,00,\00,00,50,00,49,00,4f,00,4e,00,45,00,45,00,52,00,20,00,43,00,44,00,2d,00,52,\00,4f,00,4d,00,20,00,44,00,52,00,4d,00,2d,00,36,00,32,00,34,00,58,00,20,00,\00,00,54,00,4f,00,52,00,69,00,53,00,41,00,4e,00,20,00,43,00,44,00,2d,00,52,\00,4f,00,4d,00,20,00,43,00,44,00,52,00,5f,00,43,00,33,00,36,00,00,00,00,00[HKEY_LOCAL_MACHINE\SYSTEM\CurrentControlSet\Services\Cdrom\Enum]"0"="IDE\\CdRomATAPI_CD-R/RW_6X4X32____________________6.GU____\\5&3494138e&0&0.0.0""Count"=dword:00000002"NextInstance"=dword:00000002"1"="IDE\\CdRomApachi__52X_____________________________1.13____\\5&3494138e&0&0.1.0"
3、然后点击“文件”——“另存为”。
4、选择保存路径及输入文件名“禁止CD-ROM自动运行.reg”，保存。
5、双击运行该注册表文件，当出现如下提示时点“是”即可。
方法二
1、点击开始菜单，运行，输入regedit,确定。
2、依次展开HKEY_LOCAL_MACHINE\System\觊皱筠桡CurrentControlSet\Services\CDRom。
3、然后在右侧窗口中找到Autorun，双击将其数值数据更改为0.确定即可。
