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.dll
I 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.
FixMMCDLL.BAT contains:
@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
Register
