IE重裝，兩步搞掂

1,修改註冊表

[HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Active Setup\Installed Components\{89820200-ECBD-11cf-8B85-00AA005B4383}

把右邊的IsInstalled值修改為0

HKEY_LOCAL_MACHINE\SOFTWARE\Microsoft\Active Setup\Installed Components\{44BBA840-CC51-11CF-AAFA-00AA00B6015C}

也是同樣，將IsInstalled修改為0

2，在運行中輸入以下內容就可以重新安裝IE了。

rundll32.exe setupapi,InstallHinfSection DefaultInstall 132 %windir%\Inf\ie.inf
