之前屏幕录像和截图一直用的UkeySoft Screen Recorder ，直到换了4k显示器之后发现不好使了，录像的时候直接崩溃。后来换了windows自带的snipping tool。
今天又看了下，最新版成了8.0
奔溃的问题解决了，可以录制，但是两个4k屏幕一起录制还是有问题。
使用7.0的注册信息，可以完成本地注册，但是重启之后就会提示授权校验错误：
Windows Registry Editor Version 5.00 [HKEY_LOCAL_MACHINE\SOFTWARE\WOW6432Node\GSLLC\21881] "InitTime"=dword:61250d35 "WorkMode"=dword:00000002 "Registerd"=dword:00000001 "SN"="70807-07524-21881-57632-20916-75753" "EMail"="root@obaby.org.cn" "LastTime"="20210825"
旧版本的还是32位的可执行文件，新版本已经是64位的了，直接x64dbg载入。
代码没有任何的混淆加密，对所有的CheckSNOnline函数下断点，运行：
启动后会断在下面的地址：

7.0我修改的verify.dll文件，这里直接修改主程序，将call <JMP.&CheckSNOnLine2> 一行nop掉。
修补源文件，再次运行就一切ok啦。
