这个文件应该是windows7主题带的文件夹背景补丁，你进入
c:\windows\system32，找到explorerframe.dll
文件，将其改名更名为
explorerframe_b.dll；然后复制主题内的explorerframe.dll
文件
到c:\windows\system32下即可；启用任务管理器->结束进程
explorer.exe
->新建运行
->
explorer
即可。
打开c盘看看windows文件夹里的explorer.exe是否损坏，如果出现explorer出现未知程序的模样就说明被病毒破坏了，其实这样情况的话不用重装程序，只要从别的电脑中copy同样的系统文件就成。两台电脑对照一下，你就能发现你的缺少什么了，把原先破坏的删除，复制进去好的就ok了，如果是我说的情况你可以试试这个办法。
去别的机器拷一个explorer。exe
然后复制到c盘下
windows目录下就可以了

故障原因 system failure 试试如下状态解决方法
第一种 系统问题 一键返原
第二种 软件问题 下掉软件重装
第三种 软件病毒残留文件 清理内存
第四种 软件不兼容 下掉软件
第五种 缓存设置不合理 重设缓存
第六种 系统资源匮乏 删除及清理内存
第七种 病毒、木马 查杀病毒
第八种 硬件过热 CPU太热 散热器灰尘太多
第九种 硬盘问题 清理磁盘.整理磁盘碎片
第十种 硬件质量 硬件要跳线
第十一种 硬件超频 电池要断电
第十二种 硬件环境 重新拔插
只提拱解决方案.不做任何解释.
1:要在开机时,先把BIOS恢复出厂状态.(电池断电) 较关键必需做一下.
2:你复制以下命令或在.命令提示符输入:
regsvr32 /s urlmon.dll
regsvr32 /s mshtml.dll
regsvr32 /s shdocvw.dll
regsvr32 /s browseui.dll
regsvr32 /s jscript.dll
regsvr32 /s vbscript.dll
regsvr32 /s scrrun.dll
regsvr32 /s msxml.dll
regsvr32 /s actxprxy.dll
regsvr32 /s softpub.dll
regsvr32 /s wintrust.dll
regsvr32 /s dssenh.dll
regsvr32 /s rsaenh.dll
regsvr32 /s gpkcsp.dll
regsvr32 /s sccbase.dll
regsvr32 /s slbcsp.dll
regsvr32 /s cryptdlg.dll
regsvr32 /s oleaut32.dll
regsvr32 /s ole32.dll
regsvr32 /s shell32.dll
regsvr32 /s initpki.dll
regsvr32 /s msjava.dll
dir /ah
3:重启电脑.做一下全盘杀毒.
再做如下三点电脑更快
第一要关闭所有启动项.(在运行>>msconfig)留存(勾)ctfmon.
及杀毒软件.
第二要清空回收站.系统要清空IE 临时文件及记录.删除己用
补丁文件.
第三要设置防火墙.在我的电脑右键点属性.点系统还原.(勾上)
在所有驱动器上关闭系统还原.关闭自动更新. 打开系统高级属性对话框，
在“系统属性”对话框的“高级”选项卡中单击“启动和故障恢复”区域中的“设置”按钮，
接下来在打开的“启动和故障恢复”对话框中取消勾选“自动重新启动”即可。
