打开组策略（开始－运行－gpedit.msc）却出现选择打开方式的窗口，修复方法：最简单的就是从打开方式窗口中选择mmc.exe程序（可通过“浏览”，一般位置在C:\WINDOWS\system32\），并勾选“始终使用选择的程序打开这种文件”（除非你想下次再选一次），然后就可以正常打开组策略了。这种修复方法的前提是系统存在组策略（Windows XP Home没有带组策略，就不用试了），并且mmc.exe文件存在，没有被误删或破坏。
有关组策略打开方式关联的修复方法，还可以通过注册表，把下面的内容拷入一个文本文件，然后另存为.reg文件，再双击导入注册表：

网上还有其它的修复方法：
1、将注册表（进入注册表方法：开始－运行－regedit）项HKEY_CURRENT_USER\Software\Policies\Microsoft\MMC\{8FC0B734-A0E1-11D1-A7D3-0000F87571E3}的Restrict_Run值改为0，或者HKEY_CURRENT_USER\Software\Policies\Microsoft\MMC下将 RestrictToPermittedSnapins 的值设置为 0。查了下我的电脑注册表，正常情况下，并没有HKEY_CURRENT_USER\Software\Policies\Microsoft\MMC，所以可以直接删除HKEY_CURRENT_USER\Software\Policies\Microsoft\MMC（HKEY_CURRENT_USER\Software\Policies\Microsoft可要保留下来，只删除MMC这一级）。
2、注册表HKEY_CLASSES_ROOT\CLSID\{8FC0B734-A0E1-11D1-A7D3-0000F87571E3}\InProcServer32下，把其中的默认值改成：%SystemRoot%\System32\GPEdit.dll。
以上修改注册表，可能需要重启才能生效。
3、检查环境变量： 右击“我的电脑”－属性－高级－环境变量－系统变量，检查Path值中是否有：%Systemroot%\System32;%Systemroot%;%Systemroot%\system32\WBEM。这个修复是为了让系统能自动找到mmc.exe，不过如果象文首所言直接浏览选择mmc.exe，也就不需要检查这里了，当然运行其它程序还是需要环境变量的，否则你直接运行regedit，系统就不会自动去c:\windows\system32\下寻找并执行regedit.exe。
4、开始－运行，输入regsvr32 filemgmt.dll，有时也会要求重新注册GPEdit.dll：regsvr32 GPEdit.dll。
这些一般是解决打不开组策略的方法，如果出现打开方式的窗口，还是用文首的方法比较好。
