使用方法：在chrome.dll同目录运行

没效果啊，
如果生成了chrome.dll.bak文件说明禁用成功，如果不起作用可以尝试将chrome.dll.bak覆盖chrome.dll并重新运行 os51 发表于 2017-1-8 11:14

哪里有chrome.dll.bak 唔，谢谢楼主分享 请教64位的怎么处理，本人小白 风筝不会断弦 发表于 2017-1-4 21:13

会自动识别32/64位 这个禁用后还能打开吗？

是把代码复制到记事本然后改后缀为BAT运行就可以吗 caijinqi1998 发表于 2017-1-5 12:43

禁用后会生成chrome.dll.bak文件，覆盖回去即可还原 风筝不会断弦 发表于 2017-1-5 13:22

并且要在chrome.dll同目录运行 os51 发表于 2017-1-5 13:53
