When you attempt to open Device Manager, or the Computer Management window, you receive an error similar to:
MMC cannot open the file C:\WINDOWS\system32\devmgmt.msc.
This behavior may occur if one or more library files used my the MMC are missing or corrupted:
Msxml.dll Msxml2.dll Msxml3.dllI have scripted FixMMCDLL.BAT to resolve this behavior:
1. Open a CMD.EXE window.
2. Type FixMMCDLL.BAT and press Enter.
3. Shutdown and restart your computer.
@echo off CD /D %SystemRoot%\System32 del /q Msxml.dll del /q Msxml2.dll del /q Msxml3.dll copy /Y %windir%\system32\DLLCACHE\Msxml.dll *.* copy /Y %windir%\system32\DLLCACHE\Msxml2.dll *.* copy /Y %windir%\system32\DLLCACHE\Msxml3.dll *.* regsvr32 /s Msxml.dll regsvr32 /s Msxml2.dll regsvr32 /s Msxml3.dll
