VS就会告诉我们目前环境不适合安装VS2013,必须升级IE版本到IE10.
如果不想安装IE10，有没有办法呢？
答案肯定是有的。
将下面一段文字，储存为1.bat文档，然后以管理员身份执行.
@ECHO OFF :IE10HACK REG ADD "HKLM\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer" /v Version /t REG_SZ /d "9.10.9200.16384" /f REG ADD "HKLM\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer" /v svcVersion /t REG_SZ /d "10.0.9200.16384" /f REG ADD "HKLM\SOFTWARE\Microsoft\Internet Explorer" /v Version /t REG_SZ /d "9.10.9200.16384" /f REG ADD "HKLM\SOFTWARE\Microsoft\Internet Explorer" /v svcVersion /t REG_SZ /d "10.0.9200.16384" /f GOTO EXIT :REVERTIE REG DELETE "HKLM\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer" /v svcVersion REG DELETE "HKLM\SOFTWARE\Microsoft\Internet Explorer" /v svcVersion REG ADD "HKLM\SOFTWARE\Wow6432Node\Microsoft\Internet Explorer" /v Version /t REG_SZ /d "8.0.7601.17514" /f REG ADD "HKLM\SOFTWARE\Microsoft\Internet Explorer" /v Version /t REG_SZ /d "8.0.7601.17514" /f GOTO EXIT
执行后，窗口回自动退出，然后你重新安装VS即可。
