右键菜单中的打开方式无法选择程序怎么办

解决方案如下： 把下面的代码放到记事本中去，改名为up.reg （其实文件名随意取都可以），然后双击这个up.reg,把这个内容加入到注册表中就可以了，呵呵 Windows Registry Editor Version 5.00 [HKEY_CLASSES_ROOTUnknown] "AlwaysShowExt"="" "QueryClassStore"="" [HKEY_CLASSES_ROOTUnknownshell] @="openas" [HKEY_CLASSES_ROOTUnknownshellopenas] [HKEY_CLASSES_ROOTUnknownshellopenascommand] @=hex(2):25,00,53,00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,00,74,00,25, 00,5c,00,73,00,79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,72,00,75,00, 6e,00,64,00,6c,00,6c,00,33,00,32,00,2e,00,65,00,78,00,65,00,20,00,25,00,53, 00,79,00,73,00,74,00,65,00,6d,00,52,00,6f,00,6f,00,74,00,25,00,5c,00,73,00, 79,00,73,00,74,00,65,00,6d,00,33,00,32,00,5c,00,73,00,68,00,65,00,6c,00,6c, 00,33,00,32,00,2e,00,64,00,6c,00,6c,00,2c,00,4f,00,70,00,65,00,6e,00,41,00, 73,00,5f,00,52,00,75,00,6e,00,44,00,4c,00,4c,00,20,00,25,00,31,00,00,00
