问题描述 在打开vs的时候突然弹出"The security key for this program currently stored on your system does not appear to be valid for this version of the program. Select Yes to enter a new key, or No to revert to the default setting (if any)."的提示。试了下删除注册表重装等方法，均无法解决，后按照该链接的博文,添加注册表解决。
解决方法 按照复制下面的内容到txt,并保存为A.reg的文件，注意连后缀名一起改，然后打开regedit导入此文件。
Windows Registry Editor Version 5.00
[HKEY_CURRENT_USER\Software\Licenses]

用中文进行注释，浏览代码的时候就大片的红线看着不舒服
?
原因是VA搞的鬼。
在VAssistX菜单栏->Visual Assist X Options->展开Advanced->Underlines->把underlines spelling errors in comments and strings using的勾去掉就行了
